Given that total of 16 values is 528 and sum of the squares of deviation from 33 is 9158 . The variance is

Options

  1. A562.73
  2. B570.375
  3. C574.375
  4. D572.375

Correct answer

D. 572.375

Step-by-step solution

We have n =16, x _ i =528 , and 528 16 =33 x =33 and ( x _ i - x )^2=9158 Variance = 1 n ( x _ i - x )^2= 9158 16 =527.375
