Explanation:

Step1: Identify quartiles and median from box - and - whisker plot

In a box - and - whisker plot, the left - hand side of the box is Q1, the right - hand side of the box is Q3, and the line inside the box is the median. The end of the left whisker is the minimum value (youngest age) and the end of the right whisker is the maximum value (oldest age).

For the Swim Team:

Step2: Find Q1

The left - hand side of the swim team's box is at 12. So Q1 of the swim team is 12.

Step3: Find Q3

The right - hand side of the swim team's box is at 15. So Q3 of the swim team is 15.

Step4: Find the median

The line inside the swim team's box is at 13. So the median of the swim team is 13.

Step5: Find the youngest age

The end of the left whisker of the swim team is at 9. So the age of the youngest athlete on the swim team is 9.

Step6: Find the oldest age

The end of the right whisker of the swim team is at 17. So the age of the oldest athlete on the swim team is 17.

For the Track Team:

Step7: Find Q1

The left - hand side of the track team's box is at 10. So Q1 of the track team is 10.

Step8: Find Q3

The right - hand side of the track team's box is at 13. So Q3 of the track team is 13.

Step9: Find the median

The line inside the track team's box is at 11. So the median of the track team is 11.

Step10: Find the youngest age

The end of the left whisker of the track team is at 8. So the age of the youngest athlete on the track team is 8.

Step11: Find the oldest age

The end of the right whisker of the track team is at 15. So the age of the oldest athlete on the track team is 15.
