The mean of a data set is $400 and the standard deviation is $40. according to chebyshev's theorem, what percent of the values will lie within plus or minus 1.6 standard deviations of the mean?

Chebyshev's theorem says

That is, the probability that a data point falls within standard deviations of the mean is at least .

In this case, we have

so that at least 60.94% of the values can be expected to lie within 1.6 standard deviations of $400.
