The range of the observations 20 , 28 , 40 , 12 , 30 , 15 , 50 is _____

Options

  1. A18
  2. B38
  3. C28
  4. D16

Correct answer

B. 38

Step-by-step solution

Given range is 20 , 28 , 40 , 12 , 30 , 15 , 50 Now, Least value = 12 Highest vaue = 50 Range = Highest value - Least value Range = 50 - 12 = 38 .
