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 p₁ - P₂ given counts of 229 yes out of 510 sampled for Group 1 and 479 yes out 1050 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. Best estimate: Margin of error: Confidence interval: Save for Later to
