Let \(p_{m}\) and \(p_{f}\) be the respective proportions of male and female white-crowned sparrows that return to their hatching site. Give the endpoints for a 95% confidence interval for \(p_{m}-p_{f}\) if 124 out of 894 males and 70 out of 700 females returned (The Condor, 1992, pp. 117–133). Does your result agree with the conclusion of a test of \(H_{0}: p_{1}=p_{2}\) against \(H_{1}: p_{1} \neq p_{2}\) with \(\alpha=0.05\)?
