An anthropologist wants to collect data to determine whether the two different cultural groups that occupy an isolated Pacific Island grow to be different heights. The results of his samples of the heights of adult females are as follows Group A Group B n= 120 n = 150 X= 62.7 X2 = 61.8 %3D S1= 2.5 S2 = 2.62 Do these samples constitute enough evidence to reject the null hypothesis that the heights of the two groups are the same? Set alpha to .05.
