Question

Here are summary statistics for the weights of Pepsi in randomly selected cans: n = 36, x? = 0.82408 lb, s = 0.00569 lb. Use a confidence level of 90% to complete parts (a) through (d) below. a. Identify the critical value t?/2 used for finding the margin of error. t?/2 = (Round to two decimal places as needed.) b. Find the margin of error. E = lb (Round to five decimal places as needed.) c. Find the confidence interval estimate of ?. lb < ? < lb (Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. A. Approximately 90% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound. B. One has 90% 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. C. One has 90% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can. D. There is a 90% 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.
