Question

We study the relationship between hot or cold baths and the amount of relaxation they produce. The relaxation scores from two independent samples are
Sample 1 (hot): X = 43, sX = 22.79, n = 15 Sample 2 (cold): X = 39, sX = 24.6, n = 15
(a) What are H0 and Ha?
(b) Compute tobt
(c) With a = .05, what is tcrit?
(d) What should we conclude about this relationship?
(e) Compute the confidence interval for the difference between the µs.
(f) Using our two approaches, how big of an effect does bath temperature have on relaxation?
