Explanation / Answer

34) Dependent variable = Starting Salary

Independent variable = Graduation date that is Fall 89 and Spring 90.

35) Standard deviation for fall 89 - 6027.87 is smaller than Standard deviation for Spring 90 - 7110.25.

Thus, Fall 89 has less deviation from mean.

36) Mean difference = 26015.95 - 25342.73 = 673.22

37) The question can be developed on which variable (fall 89 or spring 90) has more effect on Starting Salary. Also, it can be looked whether these two variables affect the Starting salary or not at all.
