And so we're gonna have 0.4 right over there, one minus 0.4 is times 0.6, all of that over 50. So we can already look at some choices that look interesting here. This choice and this choice both look interesting, and the main thing we have to reason through is which one has a correct critical value. Do we wanna go 1.96 standard errors above and below our sample proportion, or do we wanna go 2.576 standard errors above and below our sample proportion? And the key is the 99% confidence level. Now, if we have a 99% confidence level, one way to think about it is, so let me just do my best shot at drawing a normal distribution here. And so if you want a 99% confidence level, that means you wanna contain the 99%, the middle 99% under the curve right over here, that area.
