Two random samples of car owners were chosen. The first sample contained ni 655 men, and the second sample contained n2 = 782 women. The proportion of men who reported that they use a hands-free device for the phone calls when they are driving was -0.65, while the proportion of women who gave the same response was 2 0.58. The difference in proportions is studied. Choose the correct way of calculating the confidence interval from the options below. A 0.07 ± 0.026, where 0.07 is a value of the sample statistic and 0.026 is the standard error. (B) 0.07 ± 2-0.026, where 0.07 is a value of the sample statistic and 0.026 is the standard error. C 0.072 0.005, where z is a standard normal endpoint to give the desired level of confidence. D 0.07 tr 0.026, where C E is a t-distribution endpoint to give the desired level of confidence. 0.07 ± z. . 0.026, where zis a standard normal endpoint to give the desired level of confidence.
