But that's what this z statistic is, is, well, how many standard deviations above the assumed proportion is that? So the z statistic, and we did this in previous videos, you would find the difference between this, what we got for our sample, our sample proportion, and the assumed true proportion, so 0.33 minus 0.26, all of that over the standard deviation of the sampling distribution of the sample proportions. And we've seen that in previous videos. That is just going to be the assumed proportion, so it would be just this. It'd be the assumed population proportion times one minus the assumed population proportion over n. In this particular situation, that would be 0.26 times one minus 0.26, all of that over our n, that's our sample size, 120. And if you calculate this, this should give us approximately 1.83. So they did all of that for us.
