Given that the arithmetic mean and standard deviation of a sample of 15 observations are 24 and 0 respectively. Then which one of the following is the arithmetic mean of the smallest five observations in the data?

Options

  1. A0
  2. B8
  3. C16
  4. D24

Correct answer

D. 24

Step-by-step solution

Given, standard deviation =0 Mean =24 Since standard deviation is 0 , all observations are equal to 24 . Mean of smallest five observations =24 .
