I want to figure out is this meaningful? So is there a meaningful difference here? And what we're going to do in this video is try to come up with a 95% confidence interval for this parameter. This difference of parameters is still a parameter. We don't know what the true difference of these two population parameters are, or these two population proportions, but we're going to try to come up with a 95% confidence interval for that difference. And the way we do that, we go out and we find 1,000 likely men to vote, or men likely to vote, and 1,000 women likely to vote. So let's write this down.
