Find the z-score where $\"P=0.05\"$
\n" ); document.write( "For that probability,
\n" ); document.write( " $\"z=-1.66485\"$
\n" ); document.write( " $\"%28x-64.3%29%2F2.4=-1.66485\"$
\n" ); document.write( " $\"x-64.3=-3.94765\"$
\n" ); document.write( " $\"highlight%28x=60.35%29\"$
\n" ); document.write( "So $\"H%3C60.35\"$ $\"in\"$ is the bottom 5%.
