Near the end of the last video, I wasn't as articulate as I would like to be, mainly because I think 15 minutes into a video my brain starts to really warm up too much. But what I want to do is restate what I was trying to say. We got this confidence interval. We were confident, I'll rewrite it here, we're confident that there's a 95% chance, I'll just restate the confidence interval. So there's the 95% confidence interval for the mean of this distribution, confidence interval for the mean of that distribution, we got as being 1.91 plus or minus 1.21. And near the end of the video I tried to explain why that is neat. Because here we have, it's a confidence interval for this weird mean of the difference between the sampling mean, it seems kind of confusing, but I just want to restate what we saw in previous videos.
