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. If you look at the entire distribution like this, this is the mean right over here. This tells us that at 2.5 standard deviations above the mean, so this is 2.5 times the standard deviation of the sampling distribution, if you look at this whole area over here, if you look at the z-table, is going to be 0.9951, which tells us that just this area right over here is going to be 0.4951, which tells us that this area plus a symmetric area of that many standard deviations below the mean, if you combine them, 0.4951 times 2 gets us to 99.2. This whole area right here is 99.992. If we look at the area of 2.5 standard deviations above and below the mean, let me be careful, this isn't just 2.5, we have to add another digit of precision. This is 2.5, and the next digit of precision is given by this column over here. We have to look all the way up into the second to last column, and we have to add a digit of 8 here.
