Question

Random samples of 2009 pickup trucks with 4-cylinder, 5-cylinder, 6-cylinder, and 8-cylinder engines were obtained. Each pickup truck was tested for miles per gallons in highway driving.
Is there significant evidence to show that the mpg for pickup trucks is not the same for all four engine sizes? Use a = 0.01.
