Identify the critical value tα/2 used for finding the margin of error. tα/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 μ. enter your response here ____lb<μ<____lbs(Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. 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. B. 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. C. 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
