0:00:00.012,0:00:07.162 Well, since this value is one standard deviation above the mean, 13 plus 4.8 is 0:00:07.162,0:00:14.657 17.8. If we add another 4.8, we get 22.6. And similarly, if we subtract 4.8 from 0:00:14.657,0:00:21.928 13, we get 8.2. And then subtract another 4.8 to get 3.4. So here's our normal, 0:00:21.928,0:00:24.933 unstandardized distribution.
