1. **State the problem:** We have a dataset of wait times and want to find the percentile corresponding to a wait time of 11 minutes. 2. **Explain percentile:** The percentile rank of a value is the percentage of data points less than or equal to that value. 3. **List the data:** The combined data from the three rows is: $$20,10,13,14,11,14,17,4,27,4,8,4,3,26,18,21,1,3,3,5,5,6,10,1,22,23,10,6,7,2,1,6,6,2,4,14,15,16,4,19,3,19,26,5,3,4,7,6$$ 4. **Sort the data in ascending order:** $$1,1,1,2,2,3,3,3,3,4,4,4,4,4,5,5,5,6,6,6,6,6,7,7,8,10,10,10,11,13,14,14,14,15,16,17,18,19,19,20,21,22,23,26,26,27$$ 5. **Count total data points:** There are $n=48$ data points. 6. **Count how many data points are less than or equal to 11:** Values $\leq 11$ are: $$1,1,1,2,2,3,3,3,3,4,4,4,4,4,5,5,5,6,6,6,6,6,7,7,8,10,10,10,11$$ There are $29$ such values. 7. **Calculate percentile rank using the formula:** $$\text{Percentile} = \frac{\text{Number of values } \leq 11}{n} \times 100 = \frac{29}{48} \times 100 \approx 60.42$$ 8. **Interpretation:** A wait time of 11 minutes corresponds approximately to the 60th percentile. **Final answer:** $$\boxed{60.42\%}$$
