Data Set 2 in Appendix B is derived from research into the effects of cold and other factors on human body temperature. Use just the data in the leftmost column, representing the temperatures of 11 subjects after they sat perfectly still for a period of time. Test the claim that the mean body temperature of all healthy adults who have been sitting still is equal to 37.0°C, using a 0.05 level of significance.
Use the traditional approach summarized. Draw a graph showing the test statistic and critical values. In each case, assume that the population has a distribution that is approximately normal and that the sample is randomly selected.
