The variance of the observations 2,3,5,7,11 , 13,17,22 is

Options

  1. A43.75
  2. B48.25
  3. C80
  4. D350

Correct answer

A. 43.75

Step-by-step solution

According to the given information, aligned x & = x_i 8 = 80 8 =10 (x_i- x )^2 & =350 aligned Variance of the given observations = (x_i- x )^2 8 = 350 8 =43.75 Hence, option (a) is correct.
