If the mean of 10 observations is 50 and the sum of the squares of the deviations of the
observations from the mean is 250, then the coefficient of variation of thoseobservations is
- A 25
- B 50
- C 10
- D 5
Answer & Solution
Correct Answer
(C) 10
Step-by-step Solution
Detailed explanation
Given, number of observation, \(n=10\), Mean, \(\bar{x}=50\) and \(\sum|x i-\bar{x}|^2=250\) Variance, \(\sigma^2=\sum_{i=1}^n \frac{\left|x_i-\bar{x}\right|^2}{n}\)…
