So the expected value of that is just going to be itself. If the population mean or the expected value of X is 5, this is like saying the expected value of 5. Well the expected value of 5 is going to be 5. Which is the same thing as the expected value of X. Hopefully that makes sense. We're going to use that in a second. So we're almost done. We did the expected value of this and we have one term left.
