Animal-assisted therapy for heart patients. Refer to the American Heart Association Conference (Nov. 2005) study to gauge whether animal-assisted therapy can improve the physiological responses of heart failure patients, presented in Exercise 10.43

(p. 555). You found evidence of a difference among the treatment means for the three treatments: Group T (volunteer plus trained dog), Group V (volunteer only), and Group C (control). Conduct a Bonferroni analysis to rank the three treatment means.

Use an experimentwise error rate of a = .03. Interpret the results for the researchers. [Hint: As shown in Appendix C, the Bonferroni formula for a confidence interval for the difference 1mi - mj2 is

where a* = 2a>[1k21k - 12] is the experimentwise error rate, and k is the total number of treatment means compared.]
