USE THE INFORMATION BELOW TO ANSWER QUESTIONS 4 THRU 6 In 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. The adults 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 the true 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 4 1 pts Choose the best answer below concerning the confidence interval for the difference between the true proportions of adult females minus the true proportion of adult males who use 2 or more credit/debit cards. O p(1 - p p+ z n O P1 - P2 + z1/ P1 (1 - P1) P2(1 - P2) + n1 n2 O X1 - X2+ z + 12 O x - H Z =D Question 5 1 pts Choose from the following concerning the z-value or t-value that would be used in the interval. O t = 2.31 O z = 2.05 O z = 1.64 O z = 2.58 D Question 6 1 pts Based on the interval given, choose the most appropriate conclusion for the confidence interval. We are 96% confident that there is no statistically significant difference between the true proportion of females who use 2 or more credit/debit cards and the true proportion of males who use 2 or more credit/debit cards. We are 96% confident that the true proportion of females who use 2 or more credit/debit cards is less than the true proportion of males who use 2 or more credit/debit cards. We are 96% confident that the true proportion of females who use 2 or more credit/debit cards is more than the true proportion of males who use 2 or more credit/debit cards
