Confuzzled... Do you have a question by chance?

Given"
mean: 17,123
mean absolute deviation: 611

We simply need to add and subtract the mean absolute deviation to and from the mean value to get the possible numbers of riders for week 5 that are within the mean absolute deviation.

17,123 + 611 = 17,734
17,123 - 611 = 16,512

The number of possible riders for week 5 will be between 16,512 and 17,734.
