In 2003, Major League Baseball took steps to speed up the paly of baseball games and make games a more consistent duration. In a sample of 46 games in 2002, the average duration of a game was 2 hours and 58 minutes with a standard deviation of 37 minutes. A similar survey in 2003 of 54 games found that the average duration was 2 hours and 40 minutes with a standard deviation of 22 minutes. When testing the hypothesis (at the 5% level of significance) that the variance has been reduced, what is the test statistic? (please round your answer to 2 decimal places)
