In a random sample of 27 people, the mean commute time to work was 31.3 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distribute use a t-distribution to construct a 95% confidence interval for the population mean μ. What is the margin of error of µ? Interpret the results. The confidence interval for the population mean u is (Round to one decimal place as needed.) The margin of error of u is (Round to one decimal place as needed.) Interpret the results. CETTE OA. It can be said that 95% of people have a commute time between the bounds of the confidence interval. OB. With 95% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. OC. With 95% confidence, it can be said that the commute time is between the bounds of the confidence interval. OD. If a large sample of people are taken approximately 95% of them will have commute times between the bounds of the confidence interval.
