Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 95% confidence interval for the population mean. Interpret the results. The 95% 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. With 95% confidence, it can be said that the population mean repair cost is 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. If a large sample of mobile devices are taken approximately 95% of them will have repair costs between the bounds of the confidence interval. O D. It can be said that 95% of mobile devices have a repair cost between the bounds of the confidence interval. Statcrunch Time Remaining: 01:28:51 Next
