Question

An instructor has two sections, A and B, in a particular subject. Section A has 18 students while section B has 25 students. On the same examination, although there was no significant difference in the mean grades, section A had a standard deviation, sA of 9 while section B had a standard deviation, sB of 12. Can we conclude at the 0.01 level of significance that the variability of section B is greater than that of A?
