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
