  1. Well, the means should be exactly the same. So here it would be 7.5, and here
  2. 8.2. But the standard deviations are the population standard deviation divided
  3. by the square root of the sample size. This is 0.64 divided by the square root
  4. of 20, which is about 0.14. And here, it's 0.73 divided by the square root of
  5. 20, which is about 0.16. So, they have almost the same standard deviation. So,
  6. this is about what the sampling distributions will look like, maybe a little bit
  7. skinnier. I can't draw much skinnier than this, though.
