29. To test whether the mean math score is higher for males students than for females students, a math test was given to a group of 8th graders. The results of the test are summarized in the following table. Assume that the distribution of math scores for both groups is normally distributed with equal standard deviations. Males Females Sample size it = 14 ?)2 = 25 Mean 51 - 55.9 = 48.4 Standard deviation 81 = 12.96 82 = 12.65 Given that the test statistic is 1.526, is there enough evidence to conclude that males perform better in math than females? Test at the 5% level of significance. (a) yes, because the test statistic is in the rejection region; o) no, because the test statistic is in the rejection region: c) yes, because the test statistic is not in the rejection region; OeOG no, because the test statistic is not in the rejection region; e) a conclusion is not possible
