Question: A 95% confidence interval for p 1 p 2 given that p 1 = 0.72 with n 1 = 500 and p 2 =

A 95% confidence interval for p₁ − p₂ given that p̂₁ = 0.72 with n₁ = 500 and p̂₂ = 0.68 with n₂ = 300

Use the normal distribution to find a confidence interval for a difference in proportions p₁ − p₂ given the relevant sample results. Give the best estimate for p₁ − p₂, themargin of error, and the confidence interval. Assume the results come from random samples.
