1. **State the problem:** We have the data set of volleyball serves made: 8, 4, 11, 7, 18, 7, 6, 15, 13, 5, 14. 2. **Find the five-number summary:** minimum, Q1, median, Q3, maximum. 3. **Sort the data:** 4, 5, 6, 7, 7, 8, 11, 13, 14, 15, 18. 4. **Minimum:** The smallest value is $4$. 5. **Maximum:** The largest value is $18$. 6. **Median:** The middle value (6th in sorted list) is $8$. 7. **First quartile (Q1):** Median of lower half (4,5,6,7,7) is $6$. 8. **Third quartile (Q3):** Median of upper half (11,13,14,15,18) is $14$. 9. **Summary:** Minimum = $4$, Q1 = $6$, Median = $8$, Q3 = $14$, Maximum = $18$. 10. **Interpretation:** The box plot should have whiskers at $4$ and $18$, a box from $6$ to $14$, and a median line near $8$. 11. **Conclusion:** The lower box plot with whiskers at 4 and 18, box from 6 to 14, and median near 8 correctly represents the data. **Final answer:** The box plot with whiskers at $4$ and $18$, box from $6$ to $14$, and median near $8$ represents the data.
