It's going to be the same mean value, which is the same thing as our population proportion. We've seen this multiple times. The sampling distribution's standard deviation, so the standard deviation of the sampling distribution, we could view that as one standard deviation right over there. The standard deviation of the sampling distribution we've seen multiple times is equal to the standard deviation of our original population divided by the square root of the number of samples. We do not know this right over here. We do not know the actual standard deviation in our population. Our best estimate of that, and that's why we call it confident, we're confident that the real population proportion is going to be in this interval.
