12 – KALMAN QUIZ Parameter Update 02 RENDER V2

The answer for the new mean is just the one in the middle, and the reason is both weights over here are equivalent. So, we can take the mean between MU and NU, which is 11. Then the sigma square is two. If you take one over four plus one over four, then we get one over two. So, one over one over two equals two, which means the new variance term is half the size of the previous variance terms.
