A mаjоr depаrtment stоre chаin is interested in estimating the average amоunt its credit card customers spent on their first visit to the chain's new store in the mall. Fifteen credit card accounts were randomly sampled and analyzed. Using this sample the estimated population mean is $50.50 and the estimated population variance is 400.
