Prior to the 2022 MLB season, American League baseball teams played their games with the designated hitter rule, meaning that pitchers did not bat. The league believed that replacing the pitcher, a traditionally weak hitter, with another player in the batting order produced more runs and generated more interest among fans. Below we have the summary statistics for the average number of runs scored in American League and National League stadiums for a random sampling of games during a season prior to 2022. Histograms on runs scored by American and National league games have indicated unimodal and symmetric graphs. Can you infer that the American League games have more runs scored than the National League games?
League | Sample Size | Mean | Standard Deviation |
American | 20 | 9.40 | 5.33 |
National | 20 | 8.17 | 3.03 |
