In Major league Baseball (MLB), the American League baseball teams play their home games with the designated hitter (DH). This rule gives the team the ability to have a batter take the place in the batting order of the pitcher. The league believes that by replacing the pitcher (usually a poor hitter), there will be more hits, more runs and therefore, more interest from fans. (David “Big Papi” Ortiz of the Red Sox is an example of a modern day DH). Below are the average runs scored in the American League and National League home games during the past 14 seasons. American League 11.4 9.9 10.5 9.7 10.4 9.1 10.3 9 10.2 9.0 10 8.9 9.9 8.8 National League 10.5 9.5 10.3 9.4 10 9.1 10 9 9.7 9 9.7 8.9 9.6 8.9 a) Is there evidence to suggest that the DH does lead to increased scoring in the American League?
