Consider the frequency distribution
If the variance of this distribution is 60000 , then the coefficient of variation of the distribution is

1. 60
2. $\frac{400 \sqrt{6}}{17}$
3. $\frac{400 \sqrt{6}}{9}$
4. 595.75

Solution

$\begin{array}{rlr}C V & =\frac{\sigma}{\bar{X}} \times 100 \quad\left[\text { as } \sigma^2=60000\right] \\ & =\frac{100 \sqrt{6}}{425} \times 100=\frac{400 \sqrt{6}}{17} .\end{array}$
