Neither data set contains an outlier.
The statement "Both fast food restaurants have the same median delivery time of 40 minutes" is false.
For Fast Food 1, the median delivery time is between 39 and 40 minutes (since there are 5 values before and after the median).
For Fast Food 2, the median delivery time is between 40 and 41 minutes (since there are 3 values before and after the median).
Therefore, the medians are different for both fast food restaurants.
