Let me write this over here. So this thing right over here is 0.0217. So if we want to figure out our z-score, if we want to figure out how many standard deviations the actual sample that we got of this statistic right over here, if we want to figure out how many standard deviations that is away from our assumed mean, that the assumed mean is that there's no difference, then we just divide 0.051 by this standard deviation right over here. So let's do that. So we have 0.051 divided by this standard deviation. That was our answer up here. So I'll just do divided by our answer.
