HW #2 Q 4
Hey Dr. Guy,

I was wondering if my explanation was good enough for this question. I answered:
"It cannot be negative because there is no upper limit therefore it cannot go below zero in value."

  Rebecca G.  says:
Yes. It cannot go below 0 because the deviations from the mean are SQUARED which results in either 0 or positive values.
