Question

For two distributions, the standard deviations are \(21\) and \(14\) respectively and their coefficients of variations are \(60\) and \(70\) respectively. Which of the following is correct for their arithmetic means?

• A. \(65,13\)
• B. \(18.5,65\)
• C. \(35,20\)
• D. \(22.85,35\)

Hint:

Use \(CV=\frac{\sigma}{\bar{x}}\times100\). If \(CV\) and standard deviation are given, then \(\bar{x}=\frac{\sigma\times100}{CV}\).

Answer 1

The Correct Option is C
