Consider the situation of Exercise 10-62, and recall that the hypotheses of interest are H0: p1 = p2 versus H1: p1 ( p2.
We wish to use a = 0.01. Suppose that if p1 = 0.9 and p2 = 0.6, we wish to detect this with a high probability, say, at least 0.9. What sample sizes are required to meet this objective?
