In the traffic stops dataset, the stop_duration column tells you approximately how long the driver was detained by the officer. Unfortunately, the durations are stored as strings, such as '0-15 Min'. How can you make this data easier to analyze?

In this exercise, you'll convert the stop durations to integers. Because the precise durations are not available, you'll have to estimate the numbers using reasonable values:

Convert '0-15 Min' to 8
Convert '16-30 Min' to 23
Convert '30+ Min' to 45

Are drug-related stops on the rise?
