Question

In a random sample of four microwave ovens the mean repair cost was 60 00 and the standard deviation was 12 50 Assume the population is normally distributed and use a t distribution to construct a 95 confidence interval for the population mean u What is the margin of error of Interpret the results The 95 confidence interval for the population mean is Round to two decimal places as needed The margin of error is Round to two decimal places as needed Interpret the results Choose the correct answer below 40 11 79 89 OA It can be said that 95 of microwaves have a repair cost between the bounds of the confidence interval O B With 95 confidence it can be said that the repair cost is between the bounds of the confidence interval O C With 95 confidence it can be said that the population mean repair cost is between the bounds of the confidence interval OD If a large sample of microwaves are taken approximately 95 of them will have repair costs between the bounds of the ra sum bula e 95 unc e ma
