GPT-4o mini · Answer

To find the mean absolute deviation (MAD), Sarina needs to find the average of the absolute deviations from the mean. The divisor in this case is the number of data points, which represents how many times she is calculating the average.

In this scenario, Sarina tracked her time for 7 different nights. Therefore, the number she will use for the divisor is:

7.

So the correct answer is 7.
