Answer the last question 

K
In a random sample of 27 people, the mean commute time to work was 34.1 minutes and the standard deviation was 7.3 minutes.
Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean
What is the margin of error of µ? Interpret the results.
The confidence interval for the population mean μ is (30.6, 37.6)
(Round to one decimal place as needed.)
The margin of error of µ is 3.5
(Round to one decimal place as needed.)
Interpret the results.
K
OA. It can be said that 98% of people have a commute time between the bounds of the confidence interval.
O.B. If a large sample of people are taken approximately 98% of them will have commute times between the bounds of the
confidence interval.

O C. With 98% confidence, it can be said that the population mean commute time is between the bounds of the confidence
interval.
O D. With 98% confidence, it can be said that the commute time is between the bounds of the confidence interval.
