Eleven regions in the Congolese rain forest are randomly sampled. In each region rainfall was monitored for one year, and the following total yearly rainfalls, in centimeters, were reported: {276, 255, 255, 297, 213, 241, 269, 262, 145, 185, 209}. Assume that yearly rainfalls within the Congolese rain forest are distributed normally. Test the null hypothesis that the mean yearly rainfall of all locations in the Congolese rain forest is 200. Use a two-sided test with α = .01. State the conclusion in terms of the problem and calculate the P-value for this test.

Question
Eleven regions in the Congolese rain forest are randomly sampled. In each region
rainfall was monitored for one year, and the following total yearly rainfalls, in centimeters, were reported:
{276, 255, 255, 297, 213, 241, 269, 262, 145, 185, 209}. Assume that yearly rainfalls within the Congolese rain forest are distributed normally.
Test the null hypothesis that the mean yearly rainfall of all locations in the Congolese
rain forest is 200. Use a two-sided test with α = .01. State the conclusion in terms
of the problem and calculate the P-value for this test.
