And we do the same thing with women. We survey 1,000 women who are likely to vote, but we survey them randomly. And let's say 591 say that they will vote for the candidate, and the rest say that they will not vote for the candidate. So just here, based on our sample proportions or our sample means, it looks like there is a difference, but we still have to come up with our confidence interval. And let's just make sure we understand what we just did. We just found, so we could figure out a sample proportion over here for the men, so the sample proportion here for the men, which is really just the sample mean of this sample right over here. We have 642 1s, the rest are 0, so we have 642 in the numerator.
