Question
A left-skewed distribution has a mean of 4.99 and a standard deviation of 3.13. Use Chebyshev’s Theorem to calculate the proportion of observation you would expect to find within two standard deviations (in other words, between -2 and +2 standard deviations) from the mean
1-1/(number of SD)^2 = 75%

The mean has no effect on Chebyshev's ! Results can be inaccurate in some cases
