Algebra.Com's Answer #467758 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! 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( " |
