You can put this solution on YOUR website!
z = (x - mu)/(sigma)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = (48 - 40)/(10)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = 0.8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the z score for a raw score of 48 is z = 0.8\r
\n" ); document.write( "\n" ); document.write( "=======================================================\r
\n" ); document.write( "\n" ); document.write( "z = (x - mu)/(sigma)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = (23 - 40)/(10)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z = -1.7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the z score for a raw score of 23 is z = -1.7
\n" ); document.write( "
\n" );
