For a normal distribution <em>only, </em>for a population, not for particular sample.
proportion between 1 standard deviation, independent of μ and σ , is given by:
P(Z<1)-P(Z<-1)
=0.841345-0.158655=0.682689
=0.68 (to two places of decimal)
proportion between 2 standard deviations, independent of μ and σ , is given by:
P(Z<2)-P(Z<-2)
=0.977250-0.022750=0.954500=0.95 (to two places of decimal)
