American League baseball games are played under the designated hitter rule, meaning that weak-hitting pitchers do not come to bat. Baseball owners believe that the designated hitter rule means more runs scored, which in turn means higher attendance. Is there evidence that more fans attend games if the teams score more runs? Data collected from Major League games from both major leagues during the 2012 season have a correlation of 0.477 between Rims Scored and the Home Attendance (espn.go.com/mlb/attendance).

a) Does the scatterplot indicate that it€™s appropriate to calculate a correlation? Explain.
b) Describe the association between attendance and runs scored.
c) Does this association prove that the owners are right that more fans will come to games if the teams score more runs?
