Professor Lindquist of the Accounting Department claims that there is a much wider variability in the test scores of students taking the Accounting I final exam for non majors than there is for Accounting majors. A random sample of 13 non-majors and 10 majors was taken and with the following results: N1 = 13 S12 = 21.2 N2 = 10 S22 = 36.5 At the .05 level of significance is there evidence to support Professor Lindquist’s claim? Solution no.
