K In a random sample of 23 people, the mean commute time to work was 32.6 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. View by The confidence interval for the population mean is (Round to one decimal place as needed.) The margin of error of is (Round to one decimal place as needed.) Interpret the results. A. If a large sample of people are taken approximately 98% of them will have commute times between the bounds of the confidence interval. B. It can be said that 98% of people have a commute time between the bounds of the confidence interval. OC. With 98% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. OD. With 98% confidence, it can be said that the commute time is between the bounds of the confidence interval. SAT 23 23 30
