In the very first video I did on this, I took a sample as a size of 4. In the simulation I did in the last video, we did sample sizes of 4 and 10 and whatever else. This is a sample size of 1. So that's our sample size. So as that approaches infinity, your actual sampling distribution of the sample mean will approach a normal distribution. Now in order to actually see that normal distribution and actually prove it to yourself, you would have to do this many, many times. Remember, the normal distribution happens...
