A certain vehicle emission inspection station advertises that the wait time for customers is less than 10 minutes. A local resident wants to test this claim and collects a random sample of 64 wait times for customers at the testing station. He finds that the sample mean is 9.49 ​minutes, with a standard deviation of 4.5 minutes. Does the sample evidence support the inspection​ station's claim? Use the α=0.05 level of significance to test the advertised claim that the wait time is less than 10 minutes. What are the hypotheses for this​ test?
