Consider the given data with frequency distribution

xi38111054fi523244\begin{array}{ccccccc} x_i & 3 & 8 & 11 & 10 & 5 & 4 \\ f_i & 5 & 2 & 3 & 2 & 4 & 4 \end{array}xi​fi​​35​82​113​102​54​44​

Match each entry in List-I to the correct entries in List-II.

List - I List - II
(P) The mean of the above data is (1) 2.5
(Q) The median of the above data is (2) 5
(R) The mean deviation about the mean of the above data is (3) 6
(S) The mean deviation about the median of the above data is (4) 2.7
(5) 2.4

The correct option is:
  1. A
    (P)→(3)  (Q)→(2)  (R)→(4)  (S)→(5)(P) \rightarrow(3) ~~ (Q) \rightarrow(2) ~~ (R) \rightarrow(4) ~~ (S) \rightarrow(5)(P)→(3)  (Q)→(2)  (R)→(4)  (S)→(5)
  2. B
    (P)→(3)  (Q)→(2)  (R)→(1)  (S)→(5)(P) \rightarrow(3) ~~ (Q) \rightarrow(2) ~~ (R) \rightarrow(1) ~~ (S) \rightarrow(5)(P)→(3)  (Q)→(2)  (R)→(1)  (S)→(5)
  3. C
    (P)→(2)  (Q)→(3)  (R)→(4)  (S)→(1)(P) \rightarrow(2) ~~ (Q) \rightarrow(3) ~~ (R) \rightarrow(4) ~~ (S) \rightarrow(1)(P)→(2)  (Q)→(3)  (R)→(4)  (S)→(1)
  4. D
    (P)→(3)  (Q)→(3)  (R)→(5)  (S)→(5)(P) \rightarrow(3) ~~ (Q) \rightarrow(3) ~~ (R) \rightarrow(5) ~~ (S) \rightarrow(5)(P)→(3)  (Q)→(3)  (R)→(5)  (S)→(5)
