A certain vehicle emission inspection station advertises that the wait time for customers is less than 6 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 5.31 minutes, with a standard deviation of 2.5 minutes. Does t sample evidence support the inspection station's claim? Use the a = 0.10 level of significance to test the advertised claim that the wait time is less than 6 minutes. What are the hypotheses for this test? Ho: minutes H1: minutes (Type an integer or a decimal.) What is the value of the test statistic? (Round to two decimal places as needed.) What is the P-value? P-value = (Round to three decimal places as needed.) Use the a = 0.10 level of significance to test the advertised claim. Since the P-value is V than a, V the null hypothesis. There V sufficient evidence to conclude that the mean wait time is less than 6 minutes.
