To find the conditional relative frequency of students walking to school given that they live more than a mile away, we will focus on the students who live 1+ miles away.
From the table, the number of students who live 1+ miles away is 58. The number of those students who walk to school is 6.
The conditional relative frequency can be calculated using the formula:
\[ \text{Conditional Relative Frequency} = \frac{\text{Number of students who walk and live 1+ mile away}}{\text{Total number of students who live 1+ mile away}} \]
Substituting the numbers:
\[ \text{Conditional Relative Frequency} = \frac{6}{58} \]
Now, we calculate that value:
\[ \frac{6}{58} \approx 0.1034 \]
To express this as a percentage, we multiply by 100:
\[ 0.1034 \times 100 \approx 10.34% \]
Thus, the conditional relative frequency of students walking to school given that they live more than a mile away is approximately 10%.
So, the correct response is 10%.
