Final answer:
The difference between the greatest and the least amount of time Jason spent practicing basketball is called the range of time.
Step-by-step explanation:
The difference between the greatest and the least amount of time Jason spent practicing basketball is called the range of time. The range is calculated by subtracting the least amount of time from the greatest amount of time. It represents the total spread or difference between the two values.
For example, if Jason spent 1 hour practicing on his least day and 5 hours practicing on his greatest day, the range would be 4 hours (5 - 1 = 4).
So, in this case, the correct answer is option c: The difference is the range of time Jason spent practicing basketball.
