It's actually going to generate the random numbers according to this probability distribution function. It's going to take 5 at a time, find their means, and plot the mean. So if I click 10,000, it's going to do that 10,000 times. So it's going to take 5 numbers from here 10,000 times and find their means 10,000 times, and then plot the 10,000 means here, so let's do that. So there you go. And notice, it's already looking a lot like a normal distribution. And like I said, the original mean of my crazy distribution here was 14.45, and the mean of after doing 10,000 samples, or 10,000 trials, my mean here is 14.42.
