A shipping firm suspects that the mean life of a certain brand of tire used by its trucks is less than 30,000 miles. To check the claim, the firm randomly selects and tests 18 of these tires and gets a mean lifetime of 29,350 miles with a standard deviation of 1200 miles. At α = 0.05, test the shipping firm's claim. Round the test statistic to the nearest thousandth.
