This question: 5 point(s) possible In a random sample of five mobile devices, the mean repair cost was $70.00 and the standard deviation was $13.00. Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 99% confidence interval for the population mean. Interpret the results. The 99% confidence interval for the population mean u 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. O A. If a large sample of mobile devices are taken approximately 99% of them will have repair costs between the bounds of the confidence interval. O B. With 99% confidence, it can be said that the population mean repair cost is between the bounds of the confidence interval. O C. It can be said that 99% of mobile devices have a repair cost between the bounds of the confidence interval. O D. With 99% confidence, it can be said that the repair cost is between the bounds of the confidence interval
