In a random sample of 26 people, the mean commute time to work was 32.6 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean μ. What is the margin error of µ? Interpret the results. The confidence interval for the population mean μ is ( (Round one decimal place as needed.) The margin of error of μ is. (Round to one decimal place as needed.) Interpret the results. O A. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. O B. With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval. OC. It can be said that 99% of people have commute time between the bounds of the confidence interval. OD. If a large sample of people are taken approximately 99% f them will have commute times between the bounds of the confidence interval.
