- A 10
- B 4.8
- C 5.4
- D 5
Answer & Solution
Correct Answer
(D) 5
Step-by-step Solution
Detailed explanation
Ordered data: \(2,3,5,7,9,11,13,15,17,20\) Median \(M = \frac{9+11}{2} = 10\) Sum of absolute deviations \(\sum |x_i - M| = |2-10|+|3-10|+|5-10|+|7-10|+|9-10|+|11-10|+|13-10|+|15-10|+|17-10|+|20-10| = 8+7+5+3+1+1+3+5+7+10 = 50\) Mean Deviation…
