Here is my problem: I have two proportions. I need to test if one is 5% higher than another. I already know my null hypothesis needs to be H0: p1  p2 <= 0.05 but I have no idea how to calculate this. I know how to test for equality and how to test if one proportion is larger than another, but that's it. Any ideas?
