Most people are definitely dominant on one side of their body - either right or left. For some sports being able to use both sides is an advantage, such as batting in baseball or softball. In order to determine if there is a difference in strength between the dominant and non-dominant sides, a few switch-hitting members of some school baseball and softball teams were asked to hit from both sides of the plate during batting practice. The longest hit (in feet) from each side was recorded for each player. Does this sample indicate that there is a difference in the distance a ball is hit by batters who are switch-hitters? The p-value was 0.03.

At alpha = 0.05, does the data indicate that there is a difference in the distance that a ball is hit by batters who are switch-hitters?
A) We fail to reject the null hypothesis. We have strong evidence there is a difference in the distance that a ball is hit by batters who are switch-hitters.
B) We reject the null hypothesis. We do not have evidence there is a difference in the distance that a ball is hit by batters who are switch-hitters.
C) We reject the null hypothesis. We have strong evidence there is a difference in the distance that a ball is hit by batters who are switch-hitters.
D) We fail to reject the null hypothesis. We do not have evidence there is a difference in the distance that a ball is hit by batters who are switch-hitters.
