Or another way you could say that is that the difference, P1 minus P2, the true proportion of men voting for the candidate minus the true population proportion of women voting for the candidate, is going to be 0. That's our null hypothesis. Our alternative hypothesis is that there is a difference. Our alternative hypothesis is that there is a difference. Or that P1 does not equal P2. Or that P1 minus P2, the proportion of men voting minus the proportion of women voting, the true population proportions, do not equal 0. And we're going to test this.
