A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 26 weeks. Assume that the length of unemployment is normally distributed with population mean of 26 weeks and the population standard deviation of 3 weeks. Suppose you would like to select a random sample of 17 unemployed individuals for a follow-up study. Round the answers of following questions to 4 decimal places. a. What is the distribution of X? X - N( 26 V. 3 b. What is the distribution of ? - N( 26 0.7276V) o c. What is the probability that one randomly selected individual found a job more than 25 weeks? 0.6293 d. For 17 unemployed individuals, find the probability that the average time that they found the next job is more than 25 weeks. 0.9147 e. For part d), is the assumption of normal necessary? Yes No o

Look at this histogram of heights from the GSS, which happens to be a case where a variable is relatively close to Normally-distributed (Normal curve laid atop for reference). Although it is tough to “eyeball” standard deviations, I am going to give you a list of values that could possibly describe one standard deviation of this distribution. Only one is even in the “ballpark”. Please select it based on your knowledge of Normal distributions. a. One inch b. Four inches c. 20 inches d. 50 inches
A population of N = 5 scores has a mean of u = 20 and a standard deviation of o = 4. Which of the following is the correct Interpretation of the standard deviation? O The average distance of scores from the mean of p- 20 is 5 points. O The average distance of scores from the mean of u = 20 is 1 point. The average distance of scores from the mean of u = 20 is 4 points. O The average squared distance of scores from the mean of u = 20 is 4 points.

Q1.2 Standard Deviation of Sampling Distribution of x-bar Suppose the distribution of cholesterol levels in a population of men is approximately normally distributed with a mean of 200 mg/dL and a standard deviation of 32 mg/dL. What is the standard deviation of the sampling distribution of for n=25? Write your answer as a decimal value rounded to four decimal places. (Don't put any text or supporting work! Just the numeric value.)
For the following situation, find the mean and standard deviation of the population. List all samples (with replacement) of the given size from that population and find the mean of each. Find the mean and standard deviation of the sampling distribution and compare them with the mean and standard deviation of the population. The scores of three students in a study group on a test are 94, 93, 97. Use a sample size of 3. The mean of the population is (Round to two decimal places as needed.) C
