Question: A 95% confidence interval for a difference in proportions p 1 p 2 if the samples have n 1 = 50 with p 1

A 95% confidence interval for a difference in proportions p₁ − p₂ if the samples have n₁ = 50 with p̂₁ = 0.68 and n₂ = 80 with p̂₂ = 0.61, and the standard error is SE = 0.085

Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed.
