A concern of Major League Baseball is that games last too long. Some executives in the league's headquarters believe that the mean length of games this past year exceeded 3 hours (180 minutes). To test this, the league selected a random sample of 80 games and found the following results: = 193 minutes and s = 16 minutes. Based on these results, if the null hypothesis is tested using an alpha level equal to 0.10, which of the following is true? Question 1 options: Based on the sample data, the null hypothesis cannot be rejected. It is possible that when the hypothesis test is completed, a Type II statistical error has been made. The null hypothesis should be rejected if > 182.31. The test statistic is t = 1.2924.
