Use the normal distribution to find a confidence interval for a difference in proportions P, P, given the relevant sample results. Assume the results come from random samples. A 90% confidence interval for p-p, given that p, = 0.78 with n = 590 and p = 0.63 with #₂ = 320 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.

Question
Use the normal distribution to find a confidence interval for a difference in proportions p, P, given the relevant sample results.
Assume the results come from random samples.
A 90% confidence interval for p₁ - p₂ given that p = 0.78 with n = 590 and p = 0.63 with #₂ = 320
Give the best estimate for P₁-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: 0.78
Margin of error:
Confidence interval: i
