Janie claims that rabbits in Australia have longer ears than rabbits in Spain.

To test her claim, a randomly selected sample of rabbits was collected in each country.

The length of one ear of each rabbit was measured and the value recorded correct to the nearest millimetre (mm).

In the Australian sample, the median recorded value was 80 mm and the interquartile range was 11 mm.

The recorded values for the Spanish sample are shown in the following box and whisker diagram.
