Chapter 8, Problem 56(choose chapter or problem)
Independent random samples of n1 1265 andn2 1688 observations were selected from binomialpopulations 1 and 2, and x1 849 and x2 910 successeswere observed. a. Find a 99% confidence interval for the difference( p1 p2) in the two population proportions. Whatdoes 99% confidence mean?b. Based on the confidence interval in part a, can youconclude that there is a difference in the two binomialproportions? Explain.
