The statement best supported by the information in the box plots is:
The interquartile range of the data for men 20–40 years old is greater than the interquartile range of the data for men 50–70 years old.
This can be inferred from the length of the box in the box plots, as the interquartile range is represented by the length of the box. The longer the box, the greater the interquartile range.
