  1. Recall that the equation for a normal distribution is
  2. 1 over root 2 pi sigma squared, e to the
  3. minus x minus mu quantity squared, over 2 sigma squared,
  4. where mu is the mean and sigma is the standard
  5. deviation. Sigma squared is the variance. If we know
  6. the form of this equation. It's not hard to look
  7. at all of these equations and figure out the values
  8. for the mean. Standard deviation and variance. They are five,
  9. 12, and 144. Zero, five,
  10. and 25. Eight, one, and one. And zero, one, and one.
