So the 95% confidence interval is going to be, is going to be the difference of our means, 1.91 plus or minus this number, 1.21. So what's our confidence interval? If we subtract it, so the low end of our confidence interval, and I'm running out of space, the low end, 1.91 minus 1.21 is just, what is that? That's just.7. So the low end is.7, and then the high end, 1.91 plus 1.21, what is that? That's 2.12. Let me just make sure that my brain sometimes doesn't work properly when I'm making these videos.
