If for a distribution, (x-5)=3 and (x-5)^2=43 and total number of observations is 18 , then the variance of the distribution is

Options

  1. A2.16
  2. B3.16
  3. C2.36
  4. D3.36

Correct answer

C. 2.36

Step-by-step solution

Given (x-5)=3 and (x-5)^2=43 Number of observations (n) = 18 To Find Variance = ? aligned Variance & = (x_i- x )^2 n & = (x-5)^2 18 = 43 18 =2.36 aligned
