The correct option is A The data sets cannot be compared, as they have different IQR.
Carnival A
Median: 56
Lower quartile: 46
Upper quartile: 72
Interquartile range: 72−46=26
Carnival B
Median: 94
Lower quartile: 80
Upper quartile: 100
Interquartile range: 100−80=20
Since the IQR of both the data sets are different, we cannot compare them.
Therefore, the correct answer is option D.
