(A)1
(B)2
(C)3
(D)4
(E)5​

Answer 1

Answer: A

Explanation: In a distribution that is skewed to the right, the value of the Mean will be greater than the value of the median. Because the meaning of this distribution is 1.8 siblings, the median must be less than 1.8 siblings. The only other choice that is less than 1.8 is the value one, so the median must be one sibling.Mean will be greater than the value of the median.
