Use the normal distribution to find a confidence interval for a difference in proportions p1??p2? given the relevant sample results. Assume the results come from random samples, A 99% confidence interval for p1??p2? given counts of 109 yes out of 550 sampled for Group 1 and 463 yes out 925 sampled for Group 2. Give the best estimate for p1??p2?, the margin of error, and the confidence interval. Round your answers to three decimal places. Bestestimate: Margin of error: Confidence interval: to
