The data in the table below represent a sample of n = 53 observations of how much fuel (in gallons) is used per school bus run on a daily basis. The director of transportation claims that a typical daily school bus run might use an average of 14.505 gallons per run. The superintendent feels that the amount of fuel used is greater than 14.505 gallons per run. Using an alpha = .01 level of significance, what do you conclude? Show your work and state your appropriate conclusions. Show all your work in a logical order, state your appropriate null and alternative hypotheses, include all your answers, provide an appropriate research question and provide appropriate concluding remarks.
