1. Given that X ?and ?if you conduct a two-tailed test of ?with .05, how many times in 50 replications would you expect to obtain significant results for samples of size (a) 10? (b) 20? (c) 50? (d) 100? 2. For a two-tailed test of H ?with .05 and n 10, what is the probability of detecting a d of (a) .2? (b) .5? (c) .8? (d) What does this tell you about using samples of this size? 3. For a two-tailed test of ?with .05 and n 100, what is the probability of detecting a d of (a) .2? (b) .5? (c) .8? (d) What does this tell you about using samples of this size? (Compare with Problem 16.)
