\"x=20\",\"25\",\"30\"
\n" ); document.write( "\"mu=25\"
\n" ); document.write( "\"sigma=6\"
\n" ); document.write( "Calculate the zscore for each x.
\n" ); document.write( "Then find the probability.
\n" ); document.write( "Multiply the probability by 100 to get the patients seen.
\n" ); document.write( "I'll do one, you do the others.
\n" ); document.write( "\"z=%28x-mu%29%2Fsigma=%2820-25%29%2F6=-5%2F6=+-0.833\"
\n" ); document.write( "\"P%28-0.833%29=0.202328\"
\n" ); document.write( "\"N=100%2A0.202328=20.2\"
\n" ); document.write( "or in EXCEL it's \"=100*NORMDIST(20,25,6,TRUE)\"
