Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, x=0.82412 lb, s = 0.00574 lb. Use a confidence level of 99% to complete parts (a) through (d) below. a. Identify the critical value tx/2 used for finding the margin of error. ¹a/2 = 2.72 (Round to two decimal places as needed.) b. Find the margin of error. E = 0.00261 lb (Round to five decimal places as needed.) c. Find the confidence interval estimate of μ. 0.82152 lb<μ< 0.82672 lb (Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. OA. One has 99% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of Pepsi in a can. OB. Approximately 99% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound. OC. One has 99% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can. OD. There is a 99% chance that the true value of the population mean weight of Pepsi in a can will fall between the lower bound and the upper bound.
