Extracted text: Q1. 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 n = 120 X1= 62.7 Group B n = 150 X2 = 61.8 $z=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. 4. For a significance level of 0.05, what is the critical value? A. to.05 = 1.645 B.to.025 = 1.960 C.Zo.05 = 1.645 D.z0.025 = 1.960 E.None of these
