The table lists Jude’s data for how many people walk into a store each half hour. The mean is 22.3. Identify the absolute deviation for each missing value. Round each value to the nearest tenth.

Answer 1

Hour | Number of People

1 | 20

2 | ?

3 | 24

4 | 28

5 | ?

6 | 18

To calculate absolute deviation, we subtract the mean (22.3) from each known value and take the absolute value of the result.

For Hour 2:
|20 - 22.3| = 2.3

For Hour 5:
|18 - 22.3| = 4.3
