Consider the frequency distribution
If the variance of this distribution is 60000 , then the coefficient of variation of the distribution is
- A 60
- B \(\frac{400 \sqrt{6}}{17}\)
- C \(\frac{400 \sqrt{6}}{9}\)
- D 595.75
Answer & Solution
Correct Answer
(B) \(\frac{400 \sqrt{6}}{17}\)
Step-by-step Solution
Detailed explanation
\(\begin{array}{rlr}C V & =\frac{\sigma}{\bar{X}} \times 100 \quad\left[\text { as } \sigma^2=60000\right] \\ & =\frac{100 \sqrt{6}}{425} \times 100=\frac{400 \sqrt{6}}{17} .\end{array}\)
