\n" ); document.write( "\n" ); document.write( "invNorm(0.29) = -0.5534\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So z = -0.5534. Use this to find the raw score x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = (x-mu)/sigma
\n" ); document.write( "-0.5534 = (x - 175)/15
\n" ); document.write( "-0.5534*15 = x - 175
\n" ); document.write( "-8.301 = x - 175
\n" ); document.write( "-8.301 + 175 = x
\n" ); document.write( "166.699 = x
