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 S2 = 2.62 S1=2.5 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. 5. What is the appropriate decision and conclusion? A. Reject Ho, so there is significance evidence to conclude heights of the two groups are different. B. Fail to eject Ho, so no significance evidence to conclude heights of the two groups are different. C. Fail to reject Ho, so there significance evidence to conclude: heights of the two groups are different D. Reject Ho, so no significance evidence to conclude heights of the two groups are different.
