A researcher wants to determine if there is a significant difference between the average fuel mileages for city and highway driving for the same model of cars. Use the EPA data below from a variety of 4-door sedans built in 2015 to determine if there is a difference between the city and highway fuel mileage for the same car models using α = 0.05. Round calculations to the nearest tenths.
