Answer 1

I believe the answer is a

Answer 2

A)The median age of participants in group 2 is older than the median age of participants for group 1.

Explanation:

A median is the middle number in a data set which is written in the format of least to greatest. When there are two middle numbers, the median is the mean of these two numbers.

Hence, in the diagram it is clearly shown that the median of the 2nd group is greater than the 1st group.

So, option A is correct.
