We will test the hypothesis that p = 60% versus p > 60%. We don't know it, but actually p is 70%. With which sample size and significance level will our test have the greatest power?

▸ α = 0.05, n = 500

▸ α = 0.05, n = 200

▸ α = 0.01, n = 500

▸ The power will be the same so long as the true proportion p remains 70%.

▸ α = 0.01, n = 200
