Find the z-score.
\n" ); document.write( " $\"Z=%28x-mu%29%2Fsigma\"$
\n" ); document.write( " $\"Z=%28461-455%29%2F10.2\"$
\n" ); document.write( " $\"Z=0.5882\"$
\n" ); document.write( "For that Z score,
\n" ); document.write( " $\"P=0.7218\"$
\n" ); document.write( "So the probability we're looking for is,
\n" ); document.write( " $\"P=1-0.7218\"$
\n" ); document.write( " $\"P=0.2782\"$ \n" ); document.write( "
