You can put this solution on YOUR website!
z = (x - mu)/(sigma)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = (x - 18)/(5)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = (11 - 18)/(5)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = (-7)/(5)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = -1.4\r
