Let me make sure I got that right, 0.995. Let's look at our z-table. Where do we get 0.995 on our z-table? 0.995 is pretty close, just to have a little error. It will be right over here. This is 0.9951. Another way to think about it is 99, so this value right here gives us the whole cumulative area, up to that, up to our mean.
