And one standard deviation below the mean, so let's see, we're gonna go, if we took away two, we would go to one, and then we're gonna go take another 0.160, so it's gonna be someplace right around here. So for example, for this first pair, one comma one, what were we doing? Well, we said, all right, how many standard deviations is this below the mean? And that turns out to be negative one over 0.816. That's what we have right over here. That's what this would have calculated. And then how many standard deviations for in the Y direction?
