At a tennis tournament a statistician keeps track of every serve. The statistician reported that the mean serve speed of a particular player was 101 miles per hour​ (mph) and the standard deviation of the serve speeds was 15 mph. Assume that the statistician also gave us the information that the distribution of the serve speeds was bell shaped. What proportion of the​ player's serves are expected to be between 116 mph and 146 ​mph? Round to four decimal places.

Answers

Answer:

0.1574 = 15.74% of the​ player's serves are expected to be between 116 mph and 146 ​mph

Step-by-step explanation:

Problems of normally distributed(bell-shaped) samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

[tex]\mu = 101, \sigma = 15[/tex]

What proportion of the​ player's serves are expected to be between 116 mph and 146 ​mph?

This is the pvalue of Z when X = 146 subtracted by the pvalue of Z when X = 116. So

X = 146

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{146 - 101}{15}[/tex]

[tex]Z = 3[/tex]

[tex]Z = 3[/tex] has a pvalue of 0.9987

X = 116

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{116 - 101}{15}[/tex]

[tex]Z = 1[/tex]

[tex]Z = 1[/tex] has a pvalue of 0.8413

0.9987 - 0.8413 = 0.1574

0.1574 = 15.74% of the​ player's serves are expected to be between 116 mph and 146 ​mph

Final answer:

To find the proportion of the player's serves between 116 mph and 146 mph, calculate the z-scores and use a z-table.

Explanation:

To find the proportion of the player's serves between 116 mph and 146 mph, we need to calculate the z-scores for these values and then use a z-table.

The formula for calculating the z-score is z = (x - mean) / standard deviation. So, for 116 mph: z = (116 - 101) / 15 = 1; and for 146 mph: z = (146 - 101) / 15 = 3.

The z-score of 1 corresponds to a cumulative proportion of 0.8413 and the z-score of 3 corresponds to a cumulative proportion of 0.9987. So, the proportion of serves between 116 mph and 146 mph is 0.9987 - 0.8413 = 0.1574, rounded to four decimal places.

A research firm supplies manufacturers with estimates of the sales of their products from samples of stores. Marketing managers often look at the sales estimates and ignore sampling error. An SRS of 50 stores this month shows mean sales of 41 units of a particular appliance with a standard deviation of 11 units. During the same month last year, an SRS of 52 stores gave mean sales of 38 units of the same appliances with a standard deviation of 13 units. An increase from 38 to 41 is a rise of 7.9 % . The marketing manager is happy because sales are up 7.9 % . (a) Give a 95 % confidence interval for the difference in mean number of units of the appliance sold at all retail stores. (Enter your answer rounded to three decimal places.)

Answers

Answer:

lower interval = -1.715

upper interval = 7.715

Step-by-step explanation:

The 95% confidence interval for the difference in mean number of units of the appliance sold at all retail stores for this case is  [-1.667, 7.667]

How to find the confidence interval for difference in mean?

Supposing the samples are large, let we're given that:

For first sample:

[tex]n_1[/tex] =sample size[tex]s_1[/tex] = sample standard devation[tex]\overline{x}_1[/tex] = sample mean

For second sample:

[tex]n_2[/tex] =sample size[tex]s_2[/tex] = sample standard devation[tex]\overline{x}_2[/tex] = sample mean

Suppose the confidence level be p% = p/100 in decimal, then the level of significance would be [tex]\alpha = 1 - p/100[/tex]

Then, the margin of error would be:

[tex]MOE = Z_{\alpha/2}\sqrt{\dfrac{s_1^2}{n_1} + \dfrac{s_2^2}{n_2}}[/tex]

where [tex]Z_{\alpha/2}[/tex] is the critical value of Z at level of significance [tex]\alpha[/tex]

The confidence interval would be:

[tex]CI = \overline{x}_1 - \overline{x}_2 \pm MOE[/tex]

Thus, for this case, we're specified that:

For first sample (SRS this month):

[tex]n_1[/tex] =sample size = 50[tex]s_1[/tex] = sample standard devation = 11[tex]\overline{x}_1[/tex] = sample mean = 41

For first sample(SRS last month):

[tex]n_2[/tex] =sample size = 52[tex]s_2[/tex] = sample standard devation = 13[tex]\overline{x}_2[/tex] = sample mean = 38

Level of significance = 1 - 95/100 = 0.05

The critical value of z at 0.05 level of significance (from the tables of critical value of Z) is: [tex]Z_{0.05/2} = 1.96[/tex]

Thus, the margin of error would be:

[tex]MOE = Z_{\alpha/2}\sqrt{\dfrac{s_1^2}{n_1} + \dfrac{s_2^2}{n_2}}\\\\\\MOE = 1.96\sqrt{\dfrac{11^2}{50} + \dfrac{13^2}{52}}\\\\MOE \approx 4.667[/tex]

Thus, the confidence interval would be:

[tex]CI = \overline{x}_1 - \overline{x}_2 \pm MOE\\CI \approx 41 - 38 \pm 4.667\\CI \approx 3 \pm 4.667\\CI \approx [3 - 4.667, 3 + 4.667] = [-1.667, 7.667][/tex]

Thus, the 95% confidence interval for the difference in mean number of units of the appliance sold at all retail stores for this case is  [-1.667, 7.667]

0.80 (80 repeating) as a fraction

Answers

Answer:

  80/99

Step-by-step explanation:

When the repeat starts at the decimal point, put the digits over an equal number of 9s.

  [tex]0.\overline{80}=\boxed{\dfrac{80}{99}}[/tex]

This fraction cannot be reduced.

Final answer:

To convert the repeating decimal 0.80 (with 80 repeating) to a fraction, set up an equation where x equals the repeating decimal, then multiply by 10 and subtract the original equation to eliminate the repeating part, and solve for x to get 8/9.

Explanation:

The number 0.80 with 80 repeating is often represented as 0.8 with a line over the 8, indicating that the 8 is repeating indefinitely. To convert 0.80 repeating to a fraction, we can use the following method:

Let x equal the repeating decimal: x = 0.888...

Multiply both sides by a power of 10 to move the decimal point to the right of the repeating digits. Here, we multiply by 10: 10x = 8.888...

Subtract the original equation from this new equation to get rid of the repeating decimal: 10x - x = 8 (9x = 8).

Now solve for x: x = 8/9.

Thus, 0.80 with 80 repeating as a fraction is 8/9.

The function is linear but is not a direct variation.

What is Direct Variation?

Direct variations are defined as the functions of the form y = kx, where k is a constant.

Here when y increases, x increases and if y decreases, x also decreases.

Given is a function that passes through three points (18, 30), (14, 24) and (10, 18).

If the function is linear, the the slope must be constant.

Slope = Change in y coordinates / Change in x coordinates

Consider (18, 30) and (14, 24).

Slope = (24 - 30) / (14 - 18) = -6 / -4 = 3/2

Consider (14, 24) and (10, 18).

Slope = (18 - 24) / (10 - 14) = 3/2

Since slope is constant, function is linear.

Let y = mx + c be the equation of the function, where m is the slope and c is the y intercept.

If the function is direct variation, c = 0.

Substitute (10, 18) in to the equation.

18 = (3/2 × 10) + c

⇒ c = 3

It is not direct variation.

Hence the function is linear but is not a direct variation.

You have two jobs. One job pays nine dollars per hour and the other job pays $7.50 per hour. You worked 18 hours last week and earned $145.50. How many hours did you work at each job?

Answers

Answer:

[tex] Y =\frac{16.5}{1.5}= 11[/tex]

[tex] X = 18-11=7[/tex]

And then we conclude that for the first job he works 7 hours and for the second job 11 hours

Step-by-step explanation:

We can define the following notation:

[tex]X[/tex] represent the number of hours worked for one job

[tex]Y[/tex] represent the number of hours worked for the other job

[tex]p_x = 9[/tex] represent the hourly payment for the first job

[tex]p_y = 7.50[/tex] represent the hourly payment for the other job

And we can define the following equations:

[tex] X+ Y= 18[/tex]   (1) represent the toal number of hours worked

[tex] 9X +7.5 Y = 145.50[/tex]  (2) represent the total amount earned

From equation (1) if we solve for X we got:

[tex] X = 18-Y[/tex] (3)

Replacing equation (3) into equation (2) we got:

[tex] 9(18-Y) +7.5 Y =145.50[/tex]

And after solve the equation we can find the value of Y:

[tex] 162 -9Y +7.5 Y =145.50[/tex]

[tex]16.5 = 1.5 Y[/tex]

[tex] Y =\frac{16.5}{1.5}= 11[/tex]

And solving for X from equation (3) we got:

[tex] X = 18-11=7[/tex]

And then we conclude that for the first job he works 7 hours and for the second job 11 hours

The recycling bin in the shape of a rectangular prism is 15.5 inches long, 8 inches wide and 7 inches high. The recycling bins need to be emptied when it is 80% full. What is the total amount needed, to the nearest cubic inch, before the recycle bin is ready to empty?

Answers

Answer:

694 cubic inches

Step-by-step explanation:

Dimension of prism

Length = 15.5 inches

width =  8 inches

height =  7 inches

Volume of regular prism is given  by area of base * height

area of base  = length * width ( as bin is rectangular)

area of base  = 15.5 * 8 square inches = 124 square inches

Volume of regular prism = area of base * height

      = 124 * 7 cubic inches = 868 cubic inches

_________________________________________________

868 cubic inches is the full capacity of the recycling bin

it is given that recycling bins need to be emptied when it is 80% full

so we need to find the 80% capacity of recycling bin

80% capacity of recycling bin = 80/100 *  full capacity of the recycling bin

                  = 0.8 * 868 cubic inches = 694.4 cubic inches

694.4 cubic inches is the amount needed before the recycle bin is ready to empty .

Answers

Answer:

(a) 99% confidence interval for the percentage of girls born is [0.804 , 0.896].

(b) Yes​, the proportion of girls is significantly different from 0.50.

Step-by-step explanation:

We are given that a clinical trial tests a method designed to increase the probability of conceiving a girl.

In the study 400 babies were​ born, and 340 of them were girls.

(a) Firstly, the pivotal quantity for 99% confidence interval for the population proportion is given by;

                    P.Q. =  [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of girls born = [tex]\frac{340}{400}[/tex] = 0.85

             n = sample of babies = 400

             p = population percentage of girls born

Here for constructing 99% confidence interval we have used One-sample z proportion statistics.

So, 99% confidence interval for the population proportion, p is ;

P(-2.58 < N(0,1) < 2.58) = 0.99  {As the critical value of z at 0.5% level

                                                    of significance are -2.58 & 2.58}  

P(-2.58 < [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < 2.58) = 0.99

P( [tex]-2.58 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < [tex]{\hat p-p}[/tex] < [tex]2.58 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ) = 0.99

P( [tex]\hat p-2.58 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < p < [tex]\hat p+2.58 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ) = 0.99

99% confidence interval for p = [[tex]\hat p-2.58 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] , [tex]\hat p+2.58 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]]

= [ [tex]0.85-2.58 \times {\sqrt{\frac{0.85(1-0.85)}{400} } }[/tex] , [tex]0.85+2.58 \times {\sqrt{\frac{0.85(1-0.85)}{400} } }[/tex] ]

 = [0.804 , 0.896]

Therefore, 99% confidence interval for the percentage of girls born is [0.804 , 0.896].

(b) Let p = population proportion of girls born.

So, Null Hypothesis, [tex]H_0[/tex] : p = 0.50      {means that the proportion of girls is equal to 0.50}

Alternate Hypothesis, [tex]H_A[/tex] : p [tex]\neq[/tex] 0.50      {means that the proportion of girls is significantly different from 0.50}

The test statistics that will be used here is One-sample z proportion test statistics;

                               T.S. = [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of girls born = [tex]\frac{340}{400}[/tex] = 0.85

             n = sample of babies = 400

So, the test statistics  =  [tex]\frac{0.85-0.50}{\sqrt{\frac{0.85(1-0.85)}{400} } }[/tex]

                                     =  19.604

Now, at 0.01 significance level, the z table gives critical value of 2.3263 for right tailed test. Since our test statistics is way more than the critical value of z as 19.604 > 2.3263, so we have sufficient evidence to reject our null hypothesis due to which we reject our null hypothesis.

Therefore, we conclude that the proportion of girls is significantly different from 0.50.

Final answer:

To construct a 99% confidence interval for the percentage of girls born, calculate the sample proportion and use it to construct the confidence interval. The method appears to be effective.

Explanation:

To construct a 99% confidence interval for the percentage of girls born, we first need to calculate the sample proportion. In this case, the sample proportion of girls is 340/400 = 0.85. Using this proportion, we can construct the confidence interval using the formula.

Confidence Interval = sample proportion ± z x √((sample proportion x (1 - sample proportion)) / sample size). Calculating the confidence interval, we find that it is 0.808 to 0.892. Since this interval does not include the value of 0.5, the method appears to be effective.

A bag of chips is 24 ounces. A serving size is 3/4 ounce. How many servings are in the bag of chips?


Answers

Answer:

The correct answer to the following question will be "32 servings".

Step-by-step explanation:

The given values are,

A bag of chips = 24 ounces

Serving size = 3/4 ounces

Servings = ?

Now,

On dividing "24 ounces" by "3/4 ounce", we get

⇒  [tex]\frac{24}{\frac{3}{4}}[/tex]

⇒  [tex]24\times \frac{4}{3}[/tex]

⇒  [tex]8\times 4[/tex]

⇒  [tex]32[/tex]

Thus, the bag of chips contains "32" servings.

Final answer:

To determine the number of servings in a 24-ounce bag of chips with a serving size of 3/4 ounce, divide the total weight by the serving size, resulting in 32 servings.

Explanation:

The student has asked a question about how to calculate the number of servings in a bag of chips given its total weight and the size of each serving. This is a mathematics problem involving division.

To find out the number of servings in a 24-ounce bag of chips where each serving is 3/4 ounce, you divide the total weight of the bag by the weight of a single serving:

Number of servings = Total weight of the bag / Weight of one serving

Number of servings = 24 oz / (3/4 oz)

To divide the fractions, you multiply by the reciprocal of the serving size, which is:

Number of servings = 24 oz × (4/3)

Number of servings = 32

Therefore, there are 32 servings in the 24-ounce bag of chips.

Annual income = $67,525

Total FCIA = 15.3% of salary

Since my annual income is $67,525 the FCIA contribution = 15.3%.

But 12.4% is for Social Security.

The remaining 2.9%(15.3% - 12.4%) will be for Medicare taxes.

The total deduction for I and my employer for medicare taxes will be:

2.9% * $67,525

= $1,958.225

The total deduction for medicare would be: $1,958.23

x ^2 +y ^2 −4x+12y−24=0 What is the center of this circle ?

Answers

(2, -6) is the center of the circle.

To find the center of the circle, we need to rewrite the given equation in standard form:

[tex]x^2 - 4x + y^2 + 12y = 24[/tex]

We can complete the square to put it into the standard form:

[tex]x^2 - 4x + 4 + y^2 + 12y + 36 = 24 + 4 + 36\\\\(x - 2)^2 + (y + 6)^2 = 64[/tex]

Now we can see that the center of the circle is (2, -6).

The center of the circle represented by the equation x^2 + y^2 −4x +12y−24=0 is (2, -6), which is determined by completing the square for both x and y terms.

To determine the center of a circle given by the equation x^2 + y^2 −4x +12y−24=0, we need to complete the square for both the x and y terms.

Step 1: Rearrange the equation by grouping x terms and y terms together: x^2 −4x + y^2 +12y = 24.

Step 2: Complete the square for the x terms and y terms: (x^2 −4x + 4) + (y^2 +12y + 36) = 24 + 4 + 36.

Step 3: Simplify the equation: (x − 2)^2 + (y + 6)^2 = 64.

Step 4: In the standard form of a circle equation, (x − h)^2 + (y − k)^2 = r^2, the center is at (h, k). Therefore, the center of the given circle is (2, -6).

Step-by-step explanation:

Kirby ran three-fourths of a half mile and dropped out of the 800 meter race. Her
pace was 12 miles an hour until the point she dropped out of the race. About how
many minutes did she run approximately?

Answers

Answer:

1.88 minutes

Step-by-step explanation:

This question can be solved using speed, distance and time concept along-with use of computing fractions.

Given

Distance ran by Kirby = 3/4 of half mile

                                    = 3/4 of 1/2 mile = 3/4 * 1/2 mile = 3/8 mile.

Speed of Kirby until she dropped out of race = 12 miles/hour

Formula to calculate time = Distance/Time

substituting value of speed of Kirby and distance covered by Kirby

Time = [tex](3/8) / 12 = 3/(8*12) = 1/32 \ hour[/tex]

Since one hour has 60 minutes 1/32 hour = (1/32) * 60 minutes = 1.88 minutes
