In a random sample of 28 people, the mean commute time to work was 31.8 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. is The confidence interval for the population mean μ (Round to one decimal place as needed.) The margin of error of u is μ (Round to one decimal place as needed.) Interpret the results. A. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. B. With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval. C. It can be said that 99% of people have a commute time between the bounds of the confidence interval. D. If a large sample of people are taken approximately 99% of them will have commute times between the bounds of the confidence interval.
