If we use the sample data in Exercise 2 for constructing a 99% confidence interval, what is the number of degrees of freedom that should be used for finding the critical value of t_α/2? What is the critical value t_α/2?

Data From Exercise 2

Listed below are body temperatures from five different subjects measured at 8 AM and again at 12 AM (from Data Set 3 “Body Temperatures” in Appendix B). Find the values of d and s_d. In general, what does md represent?

Temperature (F) at 8 AM Temperature (F) at 12 AM 97.8 98.6

Temperature (F) at 8 AM Temperature (F) at 12 AM 97.8 98.6 99.0 99.5 97.4 97.5 97.4 97.3 97.5 97.6
