Current Attempt in Progress 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 90% confidence interval for p - P₂ given that p₁ = 0.20 with n₁ = 40 and ₂ = 0.40 with n₂ = 120 Give the best estimate for p, P2, the margin of error, and the confidence interval. Round your answer for the best estimate to two decimal places and round your answers for the margin of error and the confidence interval to three decimal places. Best estimate: i Margin of error: i Confidence interval: Save for Later to Attempts: 0 of 4 ur
