we need to calculate the z-value associated with 28 and then consult the table of z-values to determine the P(|X|<28)
\n" ); document.write( "note that the |X| is always > 0
\n" ); document.write( "================================================================================
\n" ); document.write( "z-value = (28 - 25) / 3 = 3/3 = 1
\n" ); document.write( "P(|X|<28) = .84 \r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
