The VP of sales at Sam's Club has been studying sales figures at some of the Ohio stores in the chain. He believes that the mean amount spent per customer visit is less at the Akron Sam's Club than it is for the Mentor Sam's Club. To test his theory, he randomly samples 43 receipts from the Akron store which yields a sample mean amount of $97.39 with a sample standard deviation of $13.56. A random sample of 45 receipts from the Mentor store results in a sample mean amount of $105. 16 with a sample standard deviation of $12.68. At the .05 level of significance, is there enough evidence to conclude that the mean amount spent per customer visit is less at the Akron Sam's Club than it is for the Mentor Sam's Club? Then develop a 95% confidence interval for the difference in the mean amount spent per customer between the Akron Sam's Club and the Mentor Sam's Club. Assume sales at Sam's Club are normally distributed. List and clearly label all eight steps. Round to 4 (FOUR) decimal places
