z=(x-mean)/sd. This will convert a N(mean, variance) into a N(0, 1) problem, where we have probabilities.
\n" ); document.write( "=(200-250)/40
\n" ); document.write( "=-50/40
\n" ); document.write( "=-1.25\r
\n" ); document.write( "\n" ); document.write( "Want the probability z<-1.25, and that is 0.1056.
