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( " |
