During the summer months, grocery stores, convenience stores, and gas stations sell bags of ice. Independent random sample of bags were obtained from various locations, and the weight (in pounds) of each was recorded. The summary statistics are given in the following table.

The ESPN Home Run Tracker computes a variety of measurements for every home run hit in Major League Baseball, including true distance, speed off bat, elevation angle, and apex. Independent random samples of home runs during the 2013 season were obtained from six different ballparks, and the true distance was recorded for each.9 HOMERUN

 a. Is there any evidence to suggest that at least two population mean home-run distances are different? Use a = 0.05.571.

 b. Do you think there are any violations in the one-way ANOVA assumptions? If so, why?

c. Do the data suggest that population mean home-run distance is greatest in one ballpark? Why do you suppose the distances tend to be greater in that ballpark?
