In order to determine the average weight of carry on luggage by passengers in airplanes, a sample of 25 pieces of carry on luggage was collected and weighed. The average weight was 18 pounds. Assume that we know the standard deviation of the population to be 7.5 pounds. a) Determine a 97% confidence interval estimate for the mean weight of the carry on luggage.
b) Determine a 95% confidence interval estimate for the mean weight of the carry on luggage.
