All of that over 5. And the way we could think about it, 8 plus 12 is 20. 9 plus 11 is another 20, so that's 40. And then we have a 50 there, add another 10. So this is, once again, going to be 50 over 5. So this has the exact same population means. Or if you don't want to worry about the word population or sample and all of that, both of these data sets have the exact same arithmetic mean.
