If the variance of the data 2,4,5,6,8,17 is 23.33 , then the variance of 4,8,10,12,16,34 will be

Options

  1. A93.32
  2. B25.33
  3. C23.33
  4. D48.66

Correct answer

A. 93.32

Step-by-step solution

We find that each element of new data is 2 times of each element in old data. Variance of old data =23.33 variance of new data =(23.33)(2)^2=93.32
