Answer
The mean can help the Airlines calculate their total flight times.
Work Step by Step
The mean can be counted by summing all the data and dividing it by the number of data: for white drivers: $\frac{30+19+12+...+23}{48}=20.98$. The median is the average of the 1 or 2 (here 2) middle data:(18+19)/2=18.5. The mean can help the Airlines calculate their total flight times.
