(2) Assuming both managers are supposed to use the same criteria to rate the salespeople, state whether you find the direction of the relationship sensible or not, and (briefly) explain your answer. 2) (20 points) Suppose that for your senior research project you decide to test the effectiveness of three different studying methods on learning. Students are randomly assigned to one of the study methods. Method A is to have students only read the textbook but not go to class. Students assigned to Method B go to class and take notes, but don't read the textbook. Students in the Method C group don't read the textbook or go to class; they just get to look at another student's class notes. Final
