Document Summary

Let two independent random variables, y1 and y2, with binomial distributions that have parameters n1 = n2 = 100, p1, and p2, respectively, be observedto be equal to y1 = 50 and y2 = 40. Determine an approximate 90% confidenceinterval for p1 " p2. Let and be independent random variables with two binomial distributions, with and. Construct the 90% confidence interval for the difference in the population proportions. Therefore, the required 90% confidence interval for the difference in proportion is, ( 0. 015, 0. 0215)
