We took 591, or we took 1,000 samples from this when we took their mean, where it's equivalent to taking a sample from the sampling distribution. Now, this distribution over here is going to be the distribution of all of the differences of the sampling proportions, or of the sample proportions. And so it will look like this. It will have some mean value. I should do this in a different color. I'll do it in green. Yellow and blue make green.
