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.
