A professor in the economics department of the college of business and economics at CSULA claims that there is much more variability in the final exam scores of students taking the introductory economics courses as a requirement than for students taking the courses as part of a major in economics. Random samples of 13 non economics majors (group 1) and 10 economics majors (group 2) are taken from the professor's class roster in his large lecture, and the following results are computed based on the final exam scores:
A) n1 = 13 S12 = 210.2
B) n2 = 10 S22 = 36.5
C) At the 0.01 level of significance, is there evidence to support the professor's claim?
