USE THE INFORMATION BELOW TO ANSWER QUESTIONS 4 THRU 6In 2020 researchers took random samples to compare the proportion of adult females to the proportion of adult males who use 2 or more credit/debit cards. Theadults were aged 21 and older and they lived in all areas of the U.S. Based on the data collected, the researchers computed a 96 percent confidence interval for thetrue difference between the proportions of adult females minus the proportion of adult males who use 2 or more credit/debit cards. The confidence interval is:(0.013, 0.049). Assume all checks have been verified.Question 4Choose the best answer below concerning the confidence interval for the difference between the true proportions of adult females minus the true proportion ofadult males who use 2 or more credit/debit cards.z=Question 5Choose from the following concerning the z-value or t-value that would be used in the interval.z-1.64t-2.31O z- 2.58

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?
A doctor claims that the mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night. To investigate, he selects a random sample of 50 high school seniors from all high schools in his county. He also selects a random sample of 50 seniors from the colleges in his county. He constructs a 95% confidence interval for the true mean difference in the number of hours of sleep for seniors in high school and seniors in college. The resulting interval is (0.57, 1.25). Based upon the interval, can the doctor conclude that mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night? yes because 1 is in the confidence interval yes because 0 is not in the confidence interval no because 1 is in the confidence interval no because 0 is not in the confidence interval
