Answer 2

Sarina tracks her time spent on homework each night for a week, in minutes. She collects the following times: 51, 60, 25, 15, 20, 5, 35. When she solves for the mean absolute deviation, what number will she use for the divisor?

Answer 3

The mean of the dataset is:

(106 + 122 + 134 + 150 + 120 + 92 + 75) / 7 = 114

To find the mean absolute deviation, we first need to find the absolute deviations from the mean:

|106 - 114| = 8
|122 - 114| = 8
|134 - 114| = 20
|150 - 114| = 36
|120 - 114| = 6
|92 - 114| = 22
|75 - 114| = 39

Then, we find the mean of these absolute deviations:

(8 + 8 + 20 + 36 + 6 + 22 + 39) / 7 = 19.8

So the answer is 19.8 (rounded to the nearest tenth).

Therefore, the correct response is:

19.8
