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 verifed. Question 4 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. Pi - P2 + z z= Question 5 Choose from the following concerning the z-value or t-value that would be used in the interval. z-1.64 t- 2.31 Oz- 2.58
