\n" ); document.write( "----
\n" ); document.write( "The z-value corresponding to the 40%ile is -0.2533
\n" ); document.write( "--------
\n" ); document.write( "Find the x associated with that z-value:
\n" ); document.write( "z = (x-u)/s
\n" ); document.write( "-0.2533 = (x-80)/24.2
\n" ); document.write( "x-80 = 24.2*-0.2533
\n" ); document.write( "x-80 = -6.1299
\n" ); document.write( "x = 73.8701
