Question 1

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

Question 2

Births A city has two hospitals, with many more births recorded at the larger hospital than at the smaller one. Records indicate that in general babies are about equally likely to be boys or girls, but the actual gender ratio varies from week to week. Which hospital is more likely to report a week when over two-thirds of the babies born were girls? Explain.
