. To find out whether the inhabitants of two South Pacific islands may be regarded a having the same racial ancestry, an anthropologist determines the cephalic in- dices of six adult males for island 1 and eight adult males for island 2, getting x¯1 = 77.4 and x¯2 = 72.2 and the corresponding standard deviations s1 = 3.3 and s2 = 2.1. (a) Test whether the equal variance assumption is reasonable at the 0.02 level of significance.
