FISH_SAMPLE2
  The weight of fish along a river is a function of position X,
    W = A * X + B
  The values of A and B are unknown, but we can measure X and W.
  Determine the average value of W for the fish in the river
  assuming it extends from 0 <= X <= 10.

  Weight formula is W = 2.85799 * x + 16.7375
  Average weight is exactly 31.0275
