Alisson is interested in testing whether the performance of girls and boys on a standardized math test differs. He collects data from 63 girls and 51 boys, who were randomly selected from a local elementary school. The mean score for girls is 76 (s = 13), and the mean score for boys is 71 (s = 8). What test should Allison use, and what are the basic results of that analysis if s_M1-M2 = 2.08 and alpha is set at .01?
