In a random sample of 25 people, the mean commute time to work was 31.8 minutes and the standard deviation was 7 2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean . What is the margin of error of ? Interpret the results. The confidence interval for the population mean wis CD- (Round to one decimal place as needed.) The margin of error of his - (Round to one decimal place as needed.) Interpret the results. OA. If a large sample of people are taken approximately 90% of them will have commute times between the bounds of the confidence interval. OB. It can be said that 90% of people have a commute time between the bounds of the confidence interval. OC. With 90% confidence, it can be said that the commute time is between the bounds of the confidence interval. OD. With 90% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
