Answer:
Part 1: 8
Part 2: ?
Step-by-step explanation:
Sum of answers in sample 2 (200) divided by partakers of sample 2 (25) equals 8
I don't know what mean absolute deviation means. If it means the difference between the two averages then the answer is 2
But if it means the difference between the difference between the average of the whole servey and the average of sample 2 then it's 1 (the average of sample 1 is 10 and the average of the whole servey is 9)

The range of the two age groups is the same.

Both data sets contain about the same amount of variation.
