And it will be approximately normal, assuming that we have a large enough sample size. And its mean, the sampling distribution of the sample mean, is going to be the same thing as the population mean. We've seen that multiple times. Same thing as the population mean. And its variance, so the variance over here, so the variance for the sample means, or the standard error of the mean, actually this isn't the standard error. This is the, I guess you could, well, standard error would be the square root of this. So if I call this the standard error mean, that's wrong.
