If the median of observations 12, 1, 8, 54, 61, 28, 45, 35, 21, 17 is M, then what is the value of 2M + 5?

Question

Rethwrit · Accepted Answer

After arranging them in ascending order,
   1,8,12,17,21,28,35,45,54,61
  Median = \frac{21+28}{2}= \frac{49}{2}
 So, 2M+5 = 54

If the median of observations 12, 1, 8, 54, 61, 28, 45, 35, 21, 17 is M, then what is the value of 2M + 5 ?
