Homework: 8.2 Use the standard normal distribution or the 1-distribution to construct a 95% confidence interval for the population mean Justify your decision. If neither distribution can be used, explain why interpret the results In a random sample of 13 mortgage institutions, the mean interest rate was 3.64% and the standard deviation was 0.41% Assume the interest rates are normally distributed Which distribution should be used to construct the confidence interval? DA Use a normal distribution because n<30 and the interest rates are normally distributed Use aldatribution because the interest rates are normally distributed and e is known OC Use a normal distribution because the interest rates are normaly distributed and e is known Use a 1 distribution because it is a random sample, e is unknown, and the interest rates are normally distributed O Cannot use the standard normal distribution or the distribution because e is unknown, n30, and the interest rates are not normally distributed Select the correct choice below and, if necessary, fil in any anewer boxes to complete your choice OA The 95% confidence interval is (Round to two decimal places as needed) B. Neither distribution can be used to construct the confidence interval
