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. We're going to do the hypothesis test with a significance level of 5%. And all that means, and we've done this multiple times, is we are going to assume the null hypothesis. And then assuming the null hypothesis is true, we're going to then figure out the probability of getting our actual difference of our sample proportions.
