5. The file anorexia-changes.txt contains two variables for 72 anorexia patients: Treatment, which names the treatment received by the patient (cognitive, family, or standard), and WeightChange, which gives the change in the patient\'s weight in pounds. Suppose we are interested in all pairwise comparisons between the treatments: cognitive vs. standard, family vs. standard, and cognitive vs. family. Perform Tukey\'s rank HSD to see which comparisons are significant at an overall significance level of 0.05. Be wary of the differing sample sizes.
