A certain vehicle emission inspection station advertises that the wait time for customers is less than 8 minutes. A local resident wants to test this claim and collects a random sample of 64 wait times for customers at the testing station. She finds that the sample mean is 7. 43 minutes, with a standard deviation of 3. 6 minutes. Does the sample evidence support the inspection station's claim? Use the alphaequals0. 005 level of significance to test the advertised claim that the wait time is less than 8 minutes
