In order to determine the average weight of carry-on luggage by passengers in airplanes, a sample of 40 pieces of carry-on luggage was collected and weighed. The average weight was 22.5 pounds. Assume that we know the standard deviation of the population to be 4.25 pounds. Also, assume the population is normally distributed. (Round your answers to three decimal places.) (a) Determine a 99% confidence interval estimate for the population mean weight (in pounds) of the carry-on luggage. pounds to pounds (b) Determine a 95% confidence interval estimate for the population mean weight (in pounds) of the carry-on luggage. pounds to pounds Submit AnswertDistribution left Binomial Distribution Oright Xz-Distribution 0 middle 0 two-tailed F-Distribution Geometric Distribution Hypergeometric Distribution Poisson Distribution This is the graph of a standard normal distribution that has a horizontal axis labeled from 5 to 5 in increments of l.
