Chapter 11.1, Problem 5E
College Basketball Coaches’ Salaries. In 2018, Mike Krzyewski and John Calipari topped the list of highest-paid college basketball coaches (Sports Illustrated website, https://www.si.com/college-basketball/20l8/03/01/highest-paid-college-basketball-coaches-salaries-mike-krzyewski-john-calipari). The sample below shows the head basketball coach’s salary for a sample of 10 schools playing NCAA Division I basketball. Salary data are in millions of dollars.
- a. Use the sample
mean for the 10 schools to estimate the population mean annual salary for head basketball coaches at colleges and universities playing NCAA Division I basketball. - b. Use the data to estimate the population standard deviation for the annual salary for head basketball coaches.
- c. What is the 95% confidence interval for the population variance?
- d. What is the 95% confidence interval for the population standard deviation?

Please help me with the following statistic question
To evaluate the success of a 1-year experimental program designed to increase the mathematical achievement of underprivileged high school seniors, a random sample of participants in the program will be selected and their mathematics scores will be compared with the previous year’s statewide average of 525 for underprivileged seniors. The researchers want to determine whether the experimental program has increased the mean achievement level over the previous year’s statewide average. If alpha=.05, what sample size is needed to have a probability of Type II error of at most .025 if the actual mean is increased to 550? From previous results, sigma=80.
