The median commuting time is 48.5 minutes.
Explicación
## Step 1The problem provides a list of commuting times for the first two weeks of the fall term. The task is to find the median commuting time. The median is the value that separates the higher half from the lower half of a data sample. In other words, it is the middle value when the data points are arranged in ascending or descending order.## Step 2To find the median, we first need to arrange the given commuting times in ascending order. The given times are: 43, 62, 49, 47, 98, 53, 55, 48, 42, 47.## Step 3After arranging these times in ascending order, we get: 42, 43, 47, 47, 48, 49, 53, 55, 62, 98.## Step 4Since there are 10 data points, the median will be the average of the 5th and 6th values. The 5th value is 48 and the 6th value is 49.## Step 5The median is calculated as the average of these two values, which is \((48 + 49) / 2 = 48.5\).
