In order to determine the average weight of carry-on luggage by passengers in airplanes, a sample of 16 pieces of carry- on luggage was weighed. The average weight was 22 pounds. Assume that we know the standard deviation of the population to be 5 pounds. Also, assume the population is normally distributed. Determine an 80% confidence interval estimate for the population mean weight of the cary-on a. luggage. b. Determine a 95% confidence interval estimate for the population mean weight of the carry-on luggage.
