1.34

To find the mean absolute deviation, first find the mean of the data set:
Mean = (5.8 + 7 + 8.1 + 9.2 + 9.9) / 5 = 8

Next, find the absolute deviations of each data point from the mean:
|5.8 - 8| = 2.2
|7 - 8| = 1
|8.1 - 8| = 0.1
|9.2 - 8| = 1.2
|9.9 - 8| = 1.9

Now, find the mean of these absolute deviations:
(2.2 + 1 + 0.1 + 1.2 + 1.9) / 5 = 1.28

Therefore, the mean absolute deviation of the data set { 5.8, 7, 8.1, 9.2, 9.9} is 1.28.
