Beyond the Answer
To find the mean travel time, you need to add up all the travel times and then divide by the number of students. Total travel time: \[ 14 + 15 + 5 + 10 + 13 + 13 + 7 + 13 = 90 \text{ minutes} \] Mean: \[ \text{Mean} = \frac{90}{8} = 11.25 \text{ minutes} \] Now, for the median, you must first arrange the travel times in ascending order: \[ 5, 7, 10, 13, 13, 13, 14, 15 \] Since there is an even number of students (8), the median will be the average of the 4th and 5th values: \[ \text{Median} = \frac{13 + 13}{2} = 13 \text{ minutes} \] So, the mean travel time is 11.3 minutes (rounded to the nearest tenth), and the median travel time is 13 minutes.
