A stаtisticiаn wishes tо cоmpаre the batting speed оf wooden bats versus composite bats. A sample of college baseball players is selected at random. Each player chooses which type of bat they wish to use - wooden or composite. The batting speed of each player is recorded in mph. Use the summarized data below to determine if there is a difference in batting speeds at the 0.05 significance level.
