1. **State the problem:** We compare two athletes' training ride distances using box-and-whisker plots with given five-number summaries.
2. **Recall the five-number summary:** minimum, first quartile (Q1), median (Q2), third quartile (Q3), maximum.
3. **Given data:**
- Athlete A: min=11, Q1=15, median=17, Q3=21, max=25
- Athlete B: min=9, Q1=15, median=20, Q3=21, max=31
4. **(a) Which athlete went on more rides longer than 15 miles?**
- Distances longer than 15 miles are above Q1.
- For Athlete A, rides longer than 15 miles are between 15 and 25.
- For Athlete B, rides longer than 15 miles are between 15 and 31.
- Since Athlete B's maximum is higher, and the upper whisker is longer, Athlete B likely had more rides longer than 15 miles.
5. **(b) Which athlete had a larger interquartile range (IQR)?**
- IQR = Q3 - Q1
- Athlete A: IQR = 21 - 15 = 6
- Athlete B: IQR = 21 - 15 = 6
- Both have the same IQR.
6. **(c) Which athlete had a greater median distance?**
- Athlete A median = 17
- Athlete B median = 20
- Athlete B has a greater median.
7. **(d) Which athlete went on the shortest training ride?**
- Athlete A min = 11
- Athlete B min = 9
- Athlete B had the shortest ride.
**Final answers:**
(a) Athlete B
(b) Both have the same IQR
(c) Athlete B
(d) Athlete B
