1. For the previous exercise, rather than increase the sample size, what else might you do to increase power? What is a negative consequence of using this strategy?
2. Given the following values for X and s: (a) X = 44, s = 10, (b) X = 43, s = 10, (c) X = 43, s = 2, test the hypothesis H0: µ = 42 with α = .05 and n = 25.
