To find the critical value for a sample size of 3 and a 95% confidence level, you use a statistical table with an alpha value of 0.05, obtaining 5.991 as the critical value.

Explanation:

The critical value corresponding to a sample size of 3 and a confidence level of 95% is 5.991.

To find this critical value, we use a standard statistical table where for a 95% confidence level, the alpha value (a) is 0.05. Look up a table of critical values for a significance level of 0.05 and a sample size of 3 to obtain 5.991 as the critical value for a two-tailed test.

Final answer:

The Quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero.

Explanation:

The Quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero.

The quadratic formula is:

x = (-b ± √(b² -4ac)) / 2a

Where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.

The quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero. The quadratic formula is derived from the standard form of a quadratic equation, which is ax² + bx + c = 0. To find the points of intersection between a line and a quadratic, we would substitute the y-component (or x-component, depending on the variable used) of the line equation into the quadratic equation and solve for the remaining variable using the quadratic formula.

Answer:

SA = 397

Step-by-step explanation:

The area of the rectangle is L x W = 18 x 7 = 126

The area of the triangle[tex]\frac{1}{3}[/tex] face is

A = [tex]\frac{1}{2}[/tex]bh

A = [tex]\frac{1}{2}[/tex] 18 x 10

A = [tex]\frac{1}{2}[/tex] 180

A = 90

Since there are two triangles the same size we times by 2

90 x 2 = 180

The triangles on the left and right sides are two other sizes compared to the other two triangles

A = [tex]\frac{1}{2}[/tex]bh

A = [tex]\frac{1}{2}[/tex] 7 x 13

A = [tex]\frac{1}{2}[/tex] 91

A = 45.5

Since there are two triangles the same size we times by 2 again so it will be 91

Than we add them up

91 + 126 + 180 = 397‬

Answer:

a) [tex]P(53<X<62)=P(\frac{53-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{62-\mu}{\sigma})=P(\frac{53-59}{3}<Z<\frac{62-59}{3})=P(-2<z<2)[/tex]

[tex]P(-2<z<2)=P(z<2)-P(z<-2)[/tex]

[tex]P(-2<z<2)=P(z<2)-P(z<-2)=0.97725-0.02275=0.9545[/tex]

b) [tex]a=59 +1.96*3=64.88[/tex]

And for the other limit we have:

[tex]a=59 -1.96*3=53.12[/tex]

And we will have 95% of the values between (53.12, 64.88)

Step-by-step explanation:

Part a

Let X the random variable of interest of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(59,3)[/tex]  

Where [tex]\mu=59[/tex] and [tex]\sigma=3[/tex]

We are interested on this probability :

[tex]P(53<X<62)[/tex]

And we can solve this using the z score:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Using the last formula we got:

[tex]P(53<X<62)=P(\frac{53-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{62-\mu}{\sigma})=P(\frac{53-59}{3}<Z<\frac{62-59}{3})=P(-2<z<2)[/tex]

And we can find this probability with this difference:

[tex]P(-2<z<2)=P(z<2)-P(z<-2)[/tex]

And uing the normal standard distribution or excel we got:

[tex]P(-2<z<2)=P(z<2)-P(z<-2)=0.97725-0.02275=0.9545[/tex]

Part b

For this part we want to find a value a, such that we satisfy this condition:

[tex]P(X>a)=0.025[/tex]   (a)

[tex]P(X<a)=0.975[/tex]   (b)

As we can see on the figure attached the z value that satisfy the condition with 0.95 of the area on the left and 0.05 of the area on the right it's z=1.96.

If we use condition (b) from previous we have this:

[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.975[/tex]  

[tex]P(z<\frac{a-\mu}{\sigma})=0.975[/tex]

But we know which value of z satisfy the previous equation so then we can do this:

[tex]z=1.96<\frac{a-59}{3}[/tex]

And if we solve for a we got

[tex]a=59 +1.96*3=64.88[/tex]

And for the other limit we have:

[tex]a=59 -1.96*3=53.12[/tex]

And we will have 95% of the values between (53.12, 64.88)

In a normal distribution with mean 59 and standard deviation 3, approximately 81.85% of the data lie between 53 and 62. And about 95% of the data lie between 53 and 65, which is two standard deviations from the mean.

In a normal distribution, about 68% of the data lie within one standard deviation of the mean, about 95% lie within two standard deviations, and about 99.7% within three standard deviations.

Part A:

The range from 53 to 62 in this case is from -2 standard deviations from the mean (56) to +1 standard deviation (62). Looking at the empirical rule, we find that about 34.13% of data fall between the mean and -1 standard deviation, and 13.59% fall between -1 and -2 standard deviations. Similarly, about 34.13% of the data fall between the mean and +1 standard deviation. Therefore, the total percentage of data lying between 53 and 62 would be

34.13% + 13.59% + 34.13% = 81.85%, so option B is the closest.

Part B:

About 95% of the data lie between two standard deviations from the mean. Therefore, you would add and subtract two times the standard deviation from the mean, which would yield 59 - 2(3) = 53 and 59 + 2(3) = 65. Thus, about 95% of the data lie between 53 and 65.

Answer:

11.17

Step-by-step explanation:

Answer:

the outlier is the point at 15

the data is skewed to the bottom because the values below the median are far more spread out; there are more extreme values that are far below the median than above the median.

Step-by-step explanation:

A) If the outlier is included in the data, the median would not significantly change.

Box Plot is a pictorial way of denoting data's distribution on the basis of Quartile 1, Quartile 3, Minimum, Median and Maximum

Outliers are the data observations or points, lying at huge significant difference (distance) from other concentrated data observation points.

Median is a Positional average, the mid point of data. It divides the data into two equal halves, 50% below it & 50% above it.

Mean is an Arithmetic Average. It is effected by extreme values like outliers. However, in this case of presence of Lower Outlier, the mean would decrease rather than increasing.

Skewness or Tail in the data denotes concentration of values in either (lower or higher side). It is not related to outliers.

Hi Samantha heres an example for both questions see if you can try add the items and find a multiple to 95 for this question then divide by 3 and distribute like this example below which answers your other question about popcorn.

Step-by-step explanation:

462 = revenue

282 = amount sold

$1 = small

$3 = large

1. we add the amounts together = $4

2. We divide 462/4 =    460/4 = 115 so we are 2 out

3. In our workings we show 4 less +2 less = 4 x 115 = 460 +2 =462-6

456

111 = small $1

456-111 = 345 + 6 = 351 ( large $3 as we were 4+2 less we add 6 = 351

351/3 = 119 large. (we divide by price $3)

111 = small.(we keep)

To find equations

we know know on our workings we have 111 +351 we can call these s and l

s111 + l351 = s111 + l119

462 = 230

462/230 = 2sl mean price.

=====

We plug in again to find 1

462/230 + 1 = 2sl(+l)+x

1s x 1^2  x  1l^2 x x = 1     we rearrange the 1

1s x 1^2  x  3l   we replace ^2 with 1

1s  x 1 x 3l = 1

1 x 3l = 1/1s

3l = 1s

====

Now we can match s and l

3 / 1 + 4 = 460l

3 / 1 = 460/4l

3 / 1 = 120l  

1 x 120-3l

1  x 117l

117 ( 351/3) = L   you cna try rewriting this ( ) plug in in a new equation just added to show you how it works.

l = 357 = L  I wrote capitals as the l looked like a number.

When we subtract total  462- 351 = s then  s = 111

When you understand minus 6 may have made things more tricky try another number where the total 462 is rounded up by 3 to 465 or 470 an work in 30's and 10's then divide by 10 may be of some help/reflection to designing equations it helps you remember alternatives to find out distribution.

2/5 on magazine and 1/3 on dance lesson then we need to add these together by converting them to same fraction multiples.

2/5 x 3 = 6/15

1/3 x 5 = 5/15

6/15 +5/15 = 11/15

11/15 of 4.50 is found by division of the multiplier (the denominator)= 15

4.50/15 = 0.3     nb/ 0.3 = 1/15 of the whole 11 we search for

Final answer:

Ahmed's movement described by the expression 6 + (negative 8) suggests he moves from the sixth floor above ground level down to the second floor below ground level.

Explanation:

The expression Ahmed uses to describe his movement in the elevator is 6 + (negative 8). To understand this expression in the context of elevator movement, 6 could represent Ahmed starting on the sixth floor above ground level. The addition of negative 8 would signify moving 8 floors downward. Thus, the expression indicates that Ahmed moves from the sixth floor down to the second floor below ground level (since 6 - 8 equals -2). The negative result corresponds to floors below ground level. Therefore, the statement that could describe Ahmed's movement is: Ahmed moves from the sixth floor above ground level down to the second floor below ground level.
