The z-score is:
\n" ); document.write( "0.32-0.30/0.01=2
\n" ); document.write( ".
\n" ); document.write( "Looking at the z-score table we find:
\n" ); document.write( "z-score of 2 = 0.9772
\n" ); document.write( "So, bolts larger than this would be:
\n" ); document.write( "1-0.9772 = 0.0228
\n" ); document.write( "Or
\n" ); document.write( "2% of bolts would be larger
\n" ); document.write( "
\n" );
