In a random sample of six microwave ovens, the mean repair cost was $60.00and the standard deviation was $11.50. Assume the population is normally distributed and use at-distribution to construct a 95%confidence interval for the population mean . What is the margin of error of ?Interpret the results.

The 95%confidence interval for the population mean is left parenthesis nothing comma nothing right parenthesis .(,).(Round to two decimal places as needed.)The margin of error is nothing.(Round to two decimal places as needed.)Interpret the results. Choose the correct answer below.

A.

If a large sample of microwaves are taken approximately 95%of them will have repair costs between the bounds of the confidence interval.

B.

It can be said that 95%of microwaves have a repair cost between the bounds of the confidence interval.

C.

With 95%confidence, it can be said that the repair cost is between the bounds of the confidence interval.

D.

With 95%confidence, it can be said that the population mean repair cost is between the bounds of the confidence interva
