To find the medians, we first need to order the data:
Class 1: 2, 4, 5, 5, 6, 7, 7, 8, 8, 10, 10, 11, 11, 12, 14
Class 2: 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 10, 10, 11, 12
Since both classes have an odd number of data points, the median is the middle value. In Class 1, the median is 8 and in Class 2, the median is 7.
The difference between the medians is 8 - 7 = 1 mile. Therefore, Class 1 has a higher median than Class 2 by 1 mile.
