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.


I PROMISE I WOULD GIVE THE BRAINLIEST TO THE LONGEST AND MOST DETAILED EXPLANATION, AND AN ADDITIONAL 20 POINTS, Please Help the Damsel in distress :[

Answer:

The mean of Sample #2 is 8

The mean absolute deviation for Sample #2 is 4.08

Step-by-step explanation:

To find the mean for Sample #2, you find the sum of the values in the set and divide it by the number of elements in that set.

18+14+0+7+5+7+10+7+6+9+12+3+14+4+11+6+0+10+9+5+0+16+11+2+4 = 200

200 ÷ 25 = 8

To find the mean absolute deviation for Sample #2, you calculate how far away each data point is from the mean using positive distances. These are the absolute deviations. Afterward, you add those deviations together and divide the sum by the number of data points.

10+6+8+1+3+1+2+1+2+1+4+5+6+4+3+2+8+2+1+3+8+8+3+6+4 = 102

102 ÷ 25 = 4.08

I hope this helps
