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 Do these samples constitute enough evidence to reject the null hypothesis that the heights of the two groups the same? Set alpha to 0.05 1.What are the appropriate null and alternative hypothesis? 2. What is the Test statistics? 3.What is the value of the test statistic? 4. For a significance level of 0.05, what is the critical value? 5.What is the appropriate decision and conclusion?
