Do political science classes require the same amount of writing as history classes? The 51 randomly selected political science classes assigned an average of 15.3 pages of essay writing for the course. The standard deviation for these 51 classes was 5.4 pages. The 58 randomly selected history classes assigned an average of 12.1 pages of essay writing for the course. The standard deviation for these 58 classes was 4.6 pages. What can be concluded at the αα = 0.01 level of significance? For this study, we should use        The null and alternative hypotheses would be:        `H0:`                      `Ha:`                  2.
