Two random samples of 25 people were asked how many 12-ounce cans of soda they consume each week. The first sample contained both males and females, aged 12-19. The second sample contained both males and females, aged 20-39. The results are shown in the table below.

Sample #1
16 11 9 12 11
10 10 8 15 0
2 15 14 7 11
5 14 20 3 11
13 7 0 5 21
Sample #2
18 14 0 7 5
7 10 7 6 9
12 3 14 4 11
16 0 10 9 5
0 16 11 2 4
Part 1: Find the mean of Sample #2.
Part 2: Find the mean absolute deviation of Sample #2.
