Aprofessor teaches a certain section of material using a lot of examples with sports and cars to illustrate. he is concerned that this may have biased his instruction to favor male students. to test this, he measures exam grades from this section of material among women ( n = 10) and men (n = 10). the mean score in the male group was 84 ± 4.0 (m ± sd); in the female group, it was 78 ± 8.0 (m ± sd) points. if the null hypothesis is that there is no difference in exam scores, then test the null hypothesis at a .05 level of significance for a two-tailed test.
