In a random sample of 28 people, the mean commute time to work was 32.4 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean . What is the margin of error of ? Interpret the results.

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. Choose the correct answer below

A.With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval.

B. It can be said that 99% of people have a commute time between the bounds of the confidence interval.

C. With 99% confidence, it can be said that the population mean commute time is 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.
