S Question: 1 pt 2 of 11 (7 complete) This Quiz: In a random sample of 17 people, the mean commute time to work was 32.9 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distributior 99% confidence interval for the population mean u. What is the margin of error of u? 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. A. With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval. O B. It can be said that 99% of people have a commute time between the bounds of the confidence interval. OC. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval, OD. If a large sample of people are taken approximately 99% of them will have commute times between the bounds of the confidence interval. Click to select your answer(s).
