   Spend a little time with Allen Edwards's Introduction to Experimental
   Method.

   I was giving my one lesson epitome.  You are making up numbers,
   at least according to Edwards' Table III - Areas under the Normal
   Curve - 1 SD includes 68.25% of scores; - 2 SD includes 95.44%

   Better read Confidence Levels too.  (I hope George J. Mouly
   is reading this...)
