So let me, so it is 3.12. So, and just be clear, there's not a pure 95% chance that the true difference of the true means lies in this. We are just confident that there's a 95% chance, and we always have to put that little confidence there because remember, we didn't actually know the population standard deviations or the population variances. We estimated them with our sample, and because of that, we don't know that it's an exact probability. We just have to say we're confident that it's a 95% probability, and that's why it's really just, we just say it's a confidence interval. It's a pure probability. But it's a pretty neat result.
