When you construct a confidence interval for the difference between two proportions, what do you use as an unbiased estimate of the difference between the two proportions? What's the formula for the standard error of the difference between the estimates of the population proportions (SE ₁-2 ) used in a confidence interval for the difference between two proportions?
