2. Assume that the average gas mileage of all automobiles is 20.2 miles per gallon. For a random sample of 60 sport utility vehicles (SUVS), the mean gas mileage is 18.8 miles per gallon with a standard deviation of 3.2 miles per gallon. Test the claim that the mean mileage of all SUVS is less than 20.2 miles per gallon. Use a 0.05 significance level. See examples in section 9.2 and use normal distribution to find the P-value. State the null and alternative hypotheses. Ho: На: Find the P-value: P-value = Make your conclusion:
