This tells us this is the mean of the sampling of the sample distribution. But we know from many, many videos that this is going to be the same thing as the population mean that we are sampling from, that each sample comes from, each of these 100 samples come from. So this is going to be equal to mu, which is going to be equal to p. So this is going to be equal to mu, which is equal to p. Now, this variance over here, the variance of this distribution, let me draw it like this. Or even better, let's say the standard deviation of this distribution. That distance right over here. The standard deviation of the sampling distribution of the sample mean, we've seen it multiple times already, it's going to be this standard deviation. It's going to be the standard deviation of our population distribution.
