Answer 1

I believe its:

B, C, D, E

*disclaimer. I am not 100% sure if this is correct, I am just sure that 2 4 6 is NOT correct*

Step-by-step explanation:

A is not correct

B is correct

C is correct (the mean is 16. so to find MAD, its 0 plus 2, plus 1 plus 1, which is 4. 4 / 4 = 1

D is correct

E is correct (mean is 4, so 2 plus 2 plus 0 plus 4 is 8, 8 /4 = 2)

F is not correct

(if this is not correct either, i sincerely apologize)
