MATH 110 Module 8 Exam Scored 100% - Portage Learning. Suppose we have independent random samples of size n1 = 615 and n2 = 505. The proportions of success in the two samples are p1= .53 and p2 = .45. Find the 90% confidence interval for the difference in the two population proportions. Answer the following questions: 1. Multiple choice: Which equation would you use to solve this problem? A. B. C. D. 2. List the values you would insert into that equation. 3. State the final answer to the problem...
