So the mean of our sampling distribution is just going to be our population proportion. We've seen that in other videos, which is equal to 0.15. And our standard deviation of our sampling distribution, of our sample proportions, is going to be equal to the square root of P times one minus P over N, which is equal to the square root of 0.15 times 0.85, all of that over our sample size, 160. So now let's get our calculator out. So I'm gonna take the square root of 0.15 times 0.85 divided by 160, and let me close those parentheses. And so what is this going to give me? So it's going to give me approximately 0.028, and I'll go to the thousands place here.
