These distributions represent marathon times for different groups.

- Which display is most likely to represent the marathon times for people aged 20–30? Explain your reasoning.
- Which display is most likely to represent the marathon times for every tenth person to cross the finish line? Explain your reasoning.
- Which display is most likely to represent the marathon times for people aged 40–50? Explain your reasoning.
