Question

Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, $\bar{x}$= 0.82406 lb, s= 0.00573 lb. Use a confidence level of 95% to complete parts (a) through (d) below. a. Identify the critical value $z_{\alpha/2}$ used for finding the margin of error. $z_{\alpha/2}$ = $\boxed{ }$ (Round to two decimal places as needed.) b. Find the margin of error. E = $\boxed{ }$ lb (Round to five decimal places as needed.) c. Find the confidence interval estimate of $\mu$. $\boxed{ }$ < $\mu$ < $\boxed{ }$ (Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. OA. 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. OB. 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. 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. OD. Approximately 95% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound.

          Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, $\bar{x}$= 0.82406 lb, s= 0.00573 lb. Use a confidence level of 95% to complete parts (a) through (d) below.
a. Identify the critical value $z_{\alpha/2}$ used for finding the margin of error.
$z_{\alpha/2}$ = $\boxed{ }$
(Round to two decimal places as needed.)
b. Find the margin of error.
E = $\boxed{ }$ lb
(Round to five decimal places as needed.)
c. Find the confidence interval estimate of $\mu$.
$\boxed{ }$ < $\mu$ < $\boxed{ }$
(Round to five decimal places as needed.)
d. Write a brief statement that interprets the confidence interval. Choose the correct answer below.
OA. 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.
OB. 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. 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.
OD. Approximately 95% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound.
