... • The standard deviation is a measure of how well we know the location of a quantity. If we know one quantity well (small s.d. and large n) then the common variance assumption carries that knowledge over to the difference – even though knowledge of the second part of the difference is much less prec ...

If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.) ...
