The data in file PriusMPG.sav consists of mileage estimates provided by 74 2006 Toyota Prius owners as reported on the website http://www.fueleconomy.gov/. Assume the data in the file represent a random sample of 2006 Toyota Prius drivers.
1. Use the variable MPG to determine if the mean gas mileage of the drivers differs from the EPA combined city/highway mpg estimate of 55.
2. The EPA derives their combined mpg estimate by assuming that the percent of city vs. highway driving is 55/45. Use the data in variable hiway to determine if the percent of highway driving reported by Prius drivers differs significantly from the EPA estimate of 45
