The following table is based on data in Data Sets 2 and 18 in Appendix B. Samples of human body temperatures in three contexts are compared. (Assume for this exercise that all three samples are independent.)
a. Construct the ANOVA table for these data.
b. Find the F critical value based on a 0.05 level of significance. What do you conclude about the claim that the three populations have the same mean body temperature?
c. Using Tukey's method of simultaneous confidence intervals, determine which pairs of means, if any, are significantly different.
