Some baseball fans believe that the number of home runs a team hits is markedly affected by the altitude of the club€™s home park. The rationale is that the air is thinner at the higher altitudes, and balls would be expected to travel farther. The following table shows the altitudes (X) of American League ballparks and the number of home runs (Y) that each team hit during a recent season (172). Calculate the sample correlation coeffient, r, using the sums below. What would you conclude?
