Chapter 8. Estimation: One or Two Populations

Unit 8.4.5. Difference between two population proportions

Exercise 8.9. Suppose that a random sample of $latex n_X$ observations from a population with proportion $latex p_X$ of successes yields a sample proportion $latex \hat p_X$ and that an independent random sample of $latex n_Y$ observations from a population with proportion $latex p_Y$ of successes produces a sample proportion $latex \hat p_Y$. Which of the Cases I-III would you apply?
