The Automobile Association of America (AAA) conducted a mileage test to compare the gasoline mileage from real-life driving done by AAA members and results of driving done according to government standards. For each of the nine automobiles in the sample, AAA conducted a test of real-life driving done by a AAA member and a test of driving done according to government standards. Assume the samples are drawn from normally distributed populations. Is the mean gasoline mileage of real-life driving different than that of driving done according to government standards at the 0.05 significance level? Find the p-value. Do not round intermediate calculations. Round your answer to five decimal places. Include the leading zero. Format: 0.00000
