We assume that we have selected two independent random samples from populations having proportions p₁ and p₂ and that p-hat₁ = 800/1000 and p-hat₂ = 950/1000

Calculate a 95% confidence interval for p₁ - p₂.

Test H_o: p₁ - p₂= 0 versus H_o: p₁ - p₂≠ 0 by using a rejection point and by setting α equal to .05.

What is the rejection point?

What is your conclusion?
