Question: A trucking firm suspects that the mean life of a certain tire it uses is less than 35,000 miles. To check the claim, the firm randomly selects and tests 18 of these tires and gets a mean lifetime of 34,400 miles with a standard deviation of 1200 miles. At \(\alpha \) = 0.05, test the trucking firm's claim.
