To find the median for each class, we need to first arrange the data in ascending order:
Class 1: 2, 4, 5, 5, 6, 7, 7, 8, 8, 10, 10, 11, 11, 12, 14
Median for Class 1 = (8 + 10) / 2 = 9
Class 2: 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 10, 10, 11, 12
Median for Class 2 = 7
The difference between the medians is 9 - 7 = 2.
Therefore, Class 1 has a higher median than Class 2 by 2 miles.
