The Environmental Protection Agency (EPA) states that a 2013 Kia Optima should get 28 miles per gallon, on average. The website www.fueleconomy.gov allows users to report the miles per gallon that they get on their vehicle. Treat the following data as a random sample of ten 2013 Kia Optima owners. The data represent the miles per gallon on their vehicle. Is there reason to believe that individuals are getting different gas mileage than the EPA states should be attained? Be sure to verify all conditions necessary to conduct the appropriate test.
