Answer:
(A) and (D)
Explanation:
Given:
Data set 1 Data set 2
Mean=54 Mean=60
MAD=4 MAD=2
Now, The means-to-MAD ratio is given as:

=

=

=

Therefore, The means-to-MAD ratio is 3.
Thus, option (A) is correct.
Also,the Mean absolute deviation of set II is somewhat similar to Mean absolute deviation of set I, therefore The distributions are somewhat similar.
Thus, option (D) is correct.
