Here are summary statistics for the weights of Pepsi in randomly selected cans: n = 36, x = 0.82409 lb, s = 0.00573 lb. Use a confidence level of 95% to complete parts (a) through (d) below. a. Identify the critical value to/2 used for finding the margin of error. ¹x/2 = (Round to two decimal places as needed.) b. Find the margin of error. E=0 Ib (Round to five decimal places as needed.) c. Find the confidence interval estimate of μ. C lb<μ< lb (Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. O A. One has 95% 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. O B. One has 95% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can. OC. There is a 95% 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. O D. Approximately 95% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound.
