Two major automobile manufacturers have produced compact cars with engines of the same size. We are interested in determining whether or not there is a significant difference in the mean MPG (miles per gallon) when testing for the fuel efficiency of these two brands of automobiles. A random sample of 30 cars from each manufacturer is selected, and 30 drivers are selected to drive each automobile for a specified distance. Download the data file that contains the results of the test (in miles per gallon). Assume the population of differences is normally distributed. (hint: Matched sample)
