Answer and Explanation

Your Answer is

Correct Answer is A

Explanation

Because the ninth number of array B is greater than 90, it must be greater than the average number of array A, so the average number of B is greater than A;

The median of array A is (80+82)÷2 = 81, the median of array B is 82, so the median of B is greater than that of A.
