Question

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.

The data is pretty evenly distributed in the age 20-39 group.
There are no outliers in either age group.
The range of the two age groups is the same.
Both data sets contain about the same amount of variation.

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)
