Suppose that we want to test the hypothesis with a significance level (alpha) of .05 that the climate has changed since industrialization. Suppose that the mean temperature throughout history is 50 degrees. During the last 40 years, the mean temperature has been 51 degrees and suppose the population standard deviation (z distributed) is 2 degrees. What can we conclude? Then construct a 95 percent confidence interval for the population mean.
