Q. 3.97
Question
If the condition for using the empirical rule is met,why should that rule be used insted of Chebyshev's rule.
Step-by-Step Solution
Verified Answer
Chebyshev's rule is a lower bound.
1Step 1: Given information
We have to tell the difference between Chebyshev's and empirical rule.
2Step 2: 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.
