Hi,

Use Chebyshev’s theorem to find what percent of the values will fall between 226 and 340 for a data set with a mean of 283 and standard deviation of 19.



226 is  (226-283)/19 = 57/19 = 3

340 is  (340-283)/19 = 57/19 = 3



According to Chebyshev's Theorem: 

"at least [1-(1/3)^2] = [1- 1/9] = 8/9 of the data lies in that interval.

   8/9 = 88.89%
