Do political science classes require less writing than history classes? The 43 randomly selected political science classes assigned an average of 14.6 pages of essay writing for the course. The standard deviation for these 43 classes was 5.9 pages. The 52 randomly selected history classes assigned an average of 15.4 pages of essay writing for the course. The standard deviation for these 52 classes was 4.5 pages. What can be concluded at the a= 0.01 level of significance?
