To determine the percentage of coach passengers who did not check bags, we need to find the number of coach passengers who did not check bags and divide it by the total number of coach passengers.
From the table:
- The number of coach passengers who did not check bags = 57
- The total number of coach passengers = checked bags + did not check bags = 81 + 57 = 138
Now, we can calculate the percentage of coach passengers who did not check bags:
\[ \text{Percentage} = \left( \frac{\text{Number of Coach Passengers who did not check bags}}{\text{Total number of Coach Passengers}} \right) \times 100 \]
\[ \text{Percentage} = \left( \frac{57}{138} \right) \times 100 \approx 41.3% \]
Thus, the percentage of coach passengers who did not check bags, rounded to the nearest tenth, is 41.3%.
