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. So what we can do is figure out what's the probability, assuming that the true proportions are equal, that the mean of the sampling distribution of this statistic is actually 0, what's the probability that we get a difference of 0.051? So what's the likelihood that we get something that extreme? And what we're going to do here is just figure out a z score for this, essentially figure out how many standard deviations away from the mean this is.
