Question

If the condition for using the empirical rule is met,why should that rule be used insted of Chebyshev's rule.

Short answer

Chebyshev's rule is a lower bound.

Step-by-step solution

Given information

We have to tell the difference between Chebyshev's and empirical rule.

Explanation

Chebyshev's rule is lower bound on the proportion of data which can be found within a certain number of standard deviations from the mean
-if the distribution is rough bell shaped then the empirical rule in general provides a better estimate than chebyshev's rule.
