So down here, I'm going to draw the sampling distribution of the sample mean when n. So when our sample size is equal to 50. So this is essentially telling us the likelihood of the different means when we are sampling 50 men from this population and taking their average water use. So let me draw that. So let's say this is the frequency, and then here are the different values. Now, the mean value of this, the mean of the sampling distribution of the sample mean, this x bar, that's really just the sample mean right over there, is equal to, it's going to be equal to, if we were to do this millions and millions of times, if we were to plot all of the means when we keep taking samples of 50 and then we were to plot them all out, we would show that this mean of distribution is actually going to be the mean of our actual population. So it's going to be the same value. I want to do it in that same blue.
