Question

Listed below are speeds (in mi/h) of cars on the New Jersey Turpike. All cars are going in the same direction, and all of the cars are from New Jersey. The speeds were measured with a radar gun and the researchers observed the races of the drivers.
The data are from Statlib and the authors are Joseph Kadane and John Lamberth. Does it appear that drivers of either race speed more than drivers of the other race?
Find the mean and median for each of the two samples; then compare the two sets of results.
