It's a baseball cliche that "pitching wins games." Test that claim based on the accompanying data. For eight randomly selected American League teams for the 2000 season, the following data compares the Earned Run Average (ERA) for the teams' pitchers (lower is considered better) and total team wins (based on data from CNN/Sports Illustrated).

Use the rank correlation coefficient to test the claim of no correlation between the two variables. Use a significance level of α = 0.05.
