Question

The coefficient of variation of Poisson distribution with mean 36 is:

• A. \(\frac{1}{6} \times 100\)
• B. \(6 \times 100\)
• C. \(4 \times 100\)
• D. \(2 \times 100\)

Hint:

For any Poisson distribution, the Coefficient of Variation can be calculated directly as:
\[ \text{CV} = \frac{1}{\sqrt{\lambda}} \times 100 \]
Since \(\lambda = 36\), \(\sqrt{\lambda} = 6\), giving \(\frac{1}{6} \times 100\) immediately.

Answer 1

The Correct Option is A
