The incomes in a certain large population of college teachers have a normal distribution with mean $75,000 and standard deviation $10,000. sixteen (16) teachers are selected at random from this population to serve on a committee. what is the probability that their average salary is more than $77,500?

Answers

Answer 1
The probability that their average salary;
standard error
= 10,000/sqrt(16)
=10,000/4
= 2500 

(77,500 - 75000)/2500
2,500/2500
= 1 
p (z > 1) = .1587

So, the probability that their average salary is more than $77,500 is 0.1587
Answer 2
Final answer:

The probability that the average salary of a randomly selected group of 16 teachers is more than $77,500, under these specific conditions, is approximately 0.15866.

Explanation:

This question pertains to statistics involving the normal distribution. The initial conditions give us an average salary of $75,000 with a standard deviation of $10,000 for a population of college teachers. The problem asks what the probability is that the average salary of a randomly selected sample of 16 teachers is more than $77,500.

To solve this, we first calculate the standard error of the mean (SEM), which is the standard deviation divided by the square root of the sample size, or $10,000/√16 = $2,500. The Z-score, which measures how many standard deviations an element is from the mean, is then (X - μ) / SEM = ($77,500 - $75,000)/$2,500 = 1.

Normally, we'd look up this value in a Z-table, but the result for a Z-score of 1 is well-known - a cumulative probability of 0.84134. This is the chance the average salary is LESS THAN $77,500. We want the chance it's MORE THAN, which is 1 - 0.84134 = 0.15866.

Significant facts about consensual encounters

Answers

Consensual encounters include situations where the police’s conduct would lead a reasonable person to believe they are free to leave or terminate the encounter. Any person must not be restraint nor be exerted any authority by an officer. It is said that consensual encounters are the least understood of police interactions. This requires least or minimal police contact. Though minimal contact is required, this does not mean that officers cannot make requests. The distinguishing factor in a consensual encounter is that a reasonable person believes that he has the right to leave any time and refuse questions posed by the officers.

When is it appropriate to use indirect rather than direct strategies when intervening with a guest?

Answers

Final answer:

Indirect strategies are appropriate for intervening with a guest in situations that require a more subtle approach.

Explanation:

Indirect strategies are often used when intervening with a guest in situations that require a more subtle approach.

For example, if a guest is behaving inappropriately, a direct strategy would involve confronting the guest directly and addressing their behavior head-on.

Assuming this is a hypothetical situation, I don't support a laissez-faire approach to the conduct of business in an economy.

According to​ statistics, a person will devote 33 years to sleeping and watching tv. the number of years sleeping will exceed the number of years watching tv by 19. over the​ lifetime, how many years will the person spend on each of these​ activities?

Answers

Let n represent the number of years watching TV.


Then let sleeping represent as n+19.


Solution for this problem is:


n+n+19=33


2n=14

n = 14 divided by 2

n=7

7 years are spent watching TV while 26 years are spent in sleeping.

 

Other solution:


To figure out how many years you spend sleeping and watching TV, you first need to take the number in total, which is 33, and subtract the number that you will exceed sleeping.33 – 19 = 14. Now that you have the number 14, you can see that 14 divided in 2 = 7. 7 +19 = 26. This leaves you with a remainder of 7 hours watching TV and 26 hours sleeping. 26 is 19 greater than 7. 7 + 26 = 33.

Final answer:

The person will spend 26 years sleeping and 7 years watching TV based on the provided statistics.

Explanation:

The entire problem is essentially a system of two linear equations which can be solved quite easily. Let's denote the number of years spent sleeping as x and the number of years spent watching TV as y. The problem gives us two equations:

x + y = 33 (This is because the total years spent on these activities add up to 33)x - y = 19 (This is because the number of years spent sleeping exceeds the number of years spent watching TV by 19).

Adding these two equations gives 2x = 52, therefore x = 26. To find y, we simply substitute x = 26 into the first equation to get y = 33 - 26 = 7.

So a person will spend 26 years sleeping and 7 years watching TV over their lifetime according to the problem.

The issue of water ownership is complicated by

Answers

Final answer:

The issue of water ownership is complicated by factors such as the lack of a higher authority, complex water laws, and domestic politics.

Explanation:

The issue of water ownership is complicated by several factors. One of the main challenges is the lack of a higher authority to resolve disputes between states when it comes to water allocation. Unlike within the borders of a sovereign state, where the government can impose a solution, between states there is no such authority, leading to anarchy.

Another factor is the complexity of water laws, which can work against efforts to conserve water. For example, the rule of capture states that landowners have the right to pump and capture water beneath their property, regardless of the effects on neighboring wells. This can create problems for the viability of aquifers.

Moreover, domestic politics can hinder bilateral or multilateral solutions, as treaties to share water resources may face opposition from interest groups within each state. Stronger states may also prioritize their own interests over sharing water with weaker states.

IF it costs 75,000 to put on an event and total revenue is 135,000 what is the profit as a percentage of revenue

Answers

135 000-75 000=60 000
60 000/135 000 = 44.444444444%

Final answer:

The profit as a percentage of revenue is 44.44%.

Explanation:

The question asks for the profit as a percentage of revenue.

To find this, we first need to calculate the profit, which is the total revenue minus the total costs.

In this scenario, the total revenue is $135,000 and the costs to put on the event are $75,000.

So, the profit is $135,000 - $75,000 = $60,000.

Next, to find the profit as a percentage of revenue, we divide the profit by the total revenue and then multiply by 100. So, it is ($60,000 / $135,000) * 100 = 44.44%.

Final answer:

Strict limitations on design tools can lead to challenges in meeting customers' needs and discourage creative solutions. However, by employing structured design processes and constraint analysis methods, designers can turn these limitations into opportunities for improvement and innovation.

Explanation:

Strict limitations on design tools can significantly affect the design process. If a designer is constrained by the tools they can use, they might struggle to develop designs that fully meet customers' needs. Limitations can lead to early design decisions that may not be optimal, potentially resulting in a design that is unfit for purpose. Furthermore, the design process is often a matter of compromise, seeking to find the best possible solution within a set of constraints. When these constraints are overly strict or unrealistic, they can prevent the exploration of creative solutions and ultimately lead to products that fail to resonate with users.

The challenge for designers is to use their creativity within these constraints and to communicate effectively with clients and stakeholders to manage expectations. A structured design process is crucial in this context, as it can help avoid the risks of overlooking important elements and make sure that the decision-making process is well-documented and transparent. Constraint analysis methods can turn limitations into opportunities for optimization. It is also essential for designers to view these limitations as a chance to learn and grow, rather than as a barrier to their creative process.

In summary, strict limitations on design tools can lead to suboptimal solutions, but with good design practices, including clear processes and constraint analysis, these limitations can become opportunities for innovation and improvement.

Mean absolute deviation, standard deviation, and variance are all measures of the __________.

Answers

Mean absolute deviation, standard deviation and variance are all measures of the variability of a data set. The absolute and mean absolute deviation display the quantity of deviation or variation that arises about the mean score. To discover the total variability in our group of data simply add up the deviation of each score from the mean. The average deviation of a score can then be considered by dividing the total by the number of scores. To calculate the deviation of a score from the mean rest on on choice of statistic whether by means of absolute deviation, variance or standard deviation.

Final answer:

Mean absolute deviation, standard deviation, and variance are measures of the spread or variability within a set of data, each highlighting different aspects of data distribution and consistency.

Explanation:

Mean absolute deviation, standard deviation, and variance are all measures of the spread or variability within a set of data. These statistical tools are essential in understanding how data points differ from the mean, indicating the distribution's consistency or variability. Mean absolute deviation is a simple measure of variability that calculates the average distance each data point is from the mean. It provides a straightforward indication of spread without squaring the deviations, making it easier to understand but less sensitive to outliers compared to variance and standard deviation. Variance, denoted as s², takes the squared differences from the mean, averaging those squared differences. This squaring process emphasizes larger deviations more than smaller ones, making it particularly sensitive to outliers. Standard deviation, the square root of variance, brings the measure of spread back to the original units of the data and is the most commonly used measure of variability, indicating the average distance of the data points from the mean.
