Answer 2

Answer:You can put this solution on YOUR website!

The numbers are between +/- 2 sd s of the mean

With Chebyshev's inequality, at least 3/4 of the numbers would be between these two.

For the one with 3 standard deviations, it would be 8/9.

----------------------

For the second part, this is 3.5 sd s on either side

1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49.

----------------

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.
