So how are we going to do this? So if we assume the null hypothesis, what does the sampling distribution of this statistic start to look like? Well, the mean, if we assume that P1 and the true population proportions are actually the same between men and women, if P1 and P2 are actually the same, then this right here is going to be 0. This right here is going to be 0. So what we can do is we can figure out that we got, when we took the proportion of men and we subtracted from that the proportion of women, so this is our sample proportion of men who are going to vote for, at least in our poll, said they would vote for the candidate. This is the proportion of women who said they would vote for the candidate. The difference between the two was 0.051.
