The Correct Answer and Explanation is:
The correct answer is:
“Of the students who ride a bike, about 76% live more than one mile away.”
Explanation
To find the correct answer, we analyze the two-way table that shows how students get to school and whether they live more than one mile away.
Step 1: Understand the Data
From the table:
- Students who walk:
- Yes (more than 1 mile): 10
- No (1 mile or less): 31
- Total: 41
- Students who bike:
- Yes (more than 1 mile): 32
- No (1 mile or less): 27
- Total: 59
- Total students who live more than 1 mile away: 42
- Total students overall: 100
Step 2: Check Each Statement
A. “Of the students who live more than one mile away, about 76% ride a bike.”
- Students who live >1 mile away: 42
- Students who live >1 mile away AND ride a bike: 32
→ 3242≈76.2%\frac{32}{42} \approx 76.2\%4232≈76.2% — This is TRUE.
B. “Of the students who ride a bike, about 76% live more than one mile away.”
- Students who ride a bike: 59
- Students who ride a bike AND live >1 mile away: 32
→ 3259≈54.2%\frac{32}{59} \approx 54.2\%5932≈54.2% — This is FALSE.
C. “Of the students who ride a bike, about 27% live less than one mile away.”
- Students who ride a bike AND live ≤1 mile: 27
→ 2759≈45.8%\frac{27}{59} \approx 45.8\%5927≈45.8% — FALSE.
D. “Of the students who live more than one mile away, about 32% ride a bike.”
- Students who live >1 mile away: 42
- Students who ride a bike AND live >1 mile away: 32
→ 3242=76.2%\frac{32}{42} = 76.2\%4232=76.2%, not 32% — FALSE.
Conclusion:
Only Statement A is correct. About 76% of students who live more than one mile from school ride a bike. This highlights that biking is the most common option among students living farther from school.
