Suppose that a manager is interested in estimating the average amount of money customers spend in her store. After sampling 36 transactions at random, she found that the average amount spent was $32.15. She then computed a 90% confidence interval to be between $29.18 and $35.12. Which statement gives a valid interpretation of the interval? O There is a 90% chance that the mean amount spent by all customers is between $29.18 and $35.12. There is a 90% chance that a randomly selected customer will spend between $29.18 and $35.12. The store manager is 90% confident that the average amount spent by the 36 sampled customers is between $ 29.18 and $35.12. The store manager is 90% confident that the average amount spent by all customers is between $29.18 and $35.12.

Twenty years ago, a very famous psychologist specializing in marriage counseling authored a book detailing the way in which she believed spouses should communicate. She is now interested in the proportion of all couples who bought her book who stayed together. For a random sample of 275 couples who bought her book, she found that 217 of them stayed together. Based on this, compute a 90% confidence interval for the proportion of all couples who bought her book who stayed together. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) What is the lower limit of the 90% confidence interval? What is the upper limit of the 90% confidence interval?

The figure to the right shows the results of a survey in which 997 adults from Country A, 1022 adults from Country B, 1013 adults from Country C, 1011 adults from Country D, and 1008 adults from Country E were asked whether national identity is strongly tied to birthplace. Construct a 95%confidence interval for the population proportion of adults who say national identity is strongly tied to birthplace for each country listed. The 95% confidence interval for the proportion of adults from Country A who say national identity is strongly tied to birthplace is ,. (Round to three decimal places as needed.)

Assume that the following samples are independent. In a random sample of 400 women, 47% favored health care reform. In a random sample of 300 men, 36% favored health care reform. Construct a 98% confidence interval for the difference between the population proportions p1 − p2 . Based on your interval, is there a significant difference between men and women’s opinions on health care reform? Explain. Calculator function:
