Question
Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, x=0.82409 lb, s = 0.00567 lb. Use a confidence level of 99% to complete parts (a) through (d) below.
Transcribed Image Text:Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, x=0.82409 lb, s = 0.00567 lb. Use a confidence level of 99% to complete parts (a) through (d) below.
¹x/2 = 0 (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 u. lb<μ< Ib (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 99% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can. OB. 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. OC. Approximately 99% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound. O D. 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.
