Solution:
1. Calculate the interquartile range (IQR):
* Given:
- Q1 = 66
- Q3 = 85

* IQR = Q3 - Q1 = 85 - 66 = 19

2. Apply the formula for the lower outlier bound:
* Lower Bound = Q1 - 1.5 \times IQR
* Lower Bound = 66 - 1.5 \times 19
* Lower Bound = 66 - 28.5
* Lower Bound = 37.5

3. The lower outlier bound rounded to one decimal place is:
37.5
