For a set of observations, if the coefficient of variation is 25 and mean is 44 , then the variance is

Options

  1. A11
  2. B121
  3. C110
  4. D19

Correct answer

B. 121

Step-by-step solution

Since, we know Co-efficient of variation = | x | 100 25= 44 100 = 25 44 100 =11 Now, variance = ^2=11^2=121
