"Among 500 males surveyed, 320 had high blood pressure. Among 450 females surveyed, 230 had high blood pressure. Perform the hypothesis test that the proportion of men is greater than the proportion of women who have had high blood pressure at 5% level of significance."

I'm not entirely sure how to even set up this problem. I know that I need to use the "H0: mu" and I know how to compare the p-value to the alpha but I'm not sure which formula to use. How do I know which formula to use and then how can I go about setting it up?
