D Question 5 0.5 pts A production manager noticed that the mean time to complete a job was 160 minutes. From a sample of 12 times, we have a = 153.6, s = 9.4. Construct a 95% confidence interval for the mean completion time. The interval is 153.6 + 2.201 x-. (147.63, 159.57). The margin of error is = 2.714. The interval is 153.6 + 2.179 X 7 (147.69, 159.51). O The interval is 153.6 + 1.645 X - 94 (149.15, 158.05). O The interval is 153.6 + 1.96 x- V12 (148.28, 158.92)
