      Using the critical value approach, we set the null and alternative hypotheses and calculate the test statistic as in part . a. The rejection region with is . The observed value, , does fall in the rejection region and H0 is rejected. The conclusion is the same is in part . a. d How did the doctor record 1 million temperatures in 1868?
