The coefficient of variation of the first 5 prime numbers is
- A \(\frac{400}{7}\)
- B \(\frac{406}{7}\)
- C \(\frac{416}{7}\)
- D \(\frac{425}{8}\)
Answer & Solution
Correct Answer
(A) \(\frac{400}{7}\)
Step-by-step Solution
Detailed explanation
First prime number is \(2,3,5,7,11\) \(\bar{x}=\frac{2+3+5+7+11}{5}=\frac{28}{5}\) \(\begin{aligned} \Sigma x_i^2 & =4+9+25+49+121=208 \\ \sigma & =\sqrt{\frac{\Sigma x_i^2}{5}-(\bar{x})^2}\end{aligned}\)…
