Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, x= 0.82412 Ib, s = 0.00572 Ib. Use a confidence level of 99% to complete parts (a) through (d) below. a. Identify the critical value t2 used for finding the margin of error. (Round to two decimal places as needed.) b. Find the margin of error. E= 0.00272 (Round to five decimal places as needed.) Ib c. Find the confidence interval estimate of p. Ib

Here are summary statistics for the weights of Pepsi in randomly selected cans: n= 36, x = 0.82412 Ib, s= 0.00572 Ib. Use a confidence level of 99% to complete parts (a) through (d) below. a. Identify the critical value t2 used for finding the margin of error. a/2 (Round to two decimal places as needed.) b. Find the margin of error. E= 0.00272 (Round to five decimal places as needed.) Ib c. Find the confidence interval estimate of u. Ib (Round to five decimal places as needed.) >l> q1 d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. O A. 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. O B. 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 interval from the lower bound to the upper bound contains the true value of the population mean weight of Pepsi in a can. O D. 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.
