According to reports from a leasing company, the average number of miles their leased cars are driven annually is 13,260miles with a standard deviation of 1500 miles. The company has recently started using new contracts that require customers to maintain the cars themselves. The business owner believes that the average number of miles the cars are driven annually under the new contractsμ, is less than 13,260miles. The owner takes a random sample of31cars under the new contracts. The cars in the sample had been driven an average of 13,092 miles. Assume that the population follows a normal distribution. Is there support for the claim, at the level of significance of0.10, that the population mean number of miles that cars are driven annually under the new contracts is less than 13,260 miles? Assume that the population standard deviation of miles driven annually was not affected by the change in contracts. Perform a one-tailed test. Then complete the following.
