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 52 degrees. During the last 30 years, the mean temperature has been 53 degrees and suppose the population standard deviation is 2 degrees. What can we conclude? Then construct a 95 percent confidence interval for the population mean.

Solutions

Expert Solution

Note : We have used 53 as sample mean because we have concluded from test that our null hypothesis is rejected.

In a hypothesis test, the significance level α (alpha) represents the threshold for how unlikely sample data has to be, assuming the null hypothesis, in order for us to reject the null hypothesis. Often alpha is taken to be 0.05, or 1/20, which means that even if the null hypothesis is true, there is a 1/20 chance that we will reject it because our sample data happens to have a P-value less than 0.05. We want to study the heights...
