1 Twelve regions in an Amazon rainforest are randomly sampled. The total yearly rainfalls, in centimeters, for these regions were reported as follows: {188, 232, 210, 198, 202, 193, 219, 202, 252, 156, 184, 222} Assume that yearly rainfalls within the Amazon rain forest are distributed normally. Test the null hypothesis that the mean yearly rainfall of all locations in the Amazon rain forest is 200. Use a two-sided test with α = .05. State the conclusion in terms of the problem. Make a decision. Fail to reject the null hypothesis Unknown Reject the null hypothesis
