Chapter 11, Problem 2(choose chapter or problem)
A random sample of n1 = 120 individuals results in x1 = 43 successes. An independent sample of n2 = 130 individuals results in x2 = 56 successes. Does this represent sufficient evidence to conclude that p1 p2 at the a = 0.01 level of significance? 3. If n1 = 31, s1 = 12, n2 = 51, and s2 = 10, test whether s1 7 s2 at the a = 0.05 level of significance.
