Algebra.Com's Answer #692066 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! The numbers are between +/- 2 sd s of the mean \n" ); document.write( "With Chebyshev's inequality, at least 3/4 of the numbers would be between these two. \n" ); document.write( "For the one with 3 standard deviations, it would be 8/9. \n" ); document.write( "---------------------- \n" ); document.write( "For the second part, this is 3.5 sd s on either side \n" ); document.write( "1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49. \n" ); document.write( "---------------- \n" ); document.write( "The second one would be wishing 18/8 or 2.25 sd s and that fraction would be 1/(9/4)^2=1/81/16 or 16/81 or 0.1975. \n" ); document.write( " |
