The value 64 cm comes from a population with mean 50 cm
\n" ); document.write( "and standard deviation 5 cm.
\n" ); document.write( "---
\n" ); document.write( "z(64) = (64-50)/5 = 14/5 = 2.8
\n" ); document.write( "64 is 2.8 standard deviations above the mean of its population.\r
\n" ); document.write( "\n" ); document.write( "-----
\n" ); document.write( " The value 40 inches comes from a population with mean 30 inches and standard deviation 3 inches.
\n" ); document.write( "---
\n" ); document.write( "z(40)=(40-30)/3 = 3.3333...
\n" ); document.write( "40 is 3 1/3 standard deviations above the mean of its population
\n" ); document.write( "==========================
