Answer:
6°C
Step-by-step explanation:
The range of a data set is the difference between the maximum and minimum values.
In this case, the maximum temperature is 24°C and the minimum temperature is 18°C. Therefore, the range is:
Range = Maximum value - Minimum value
Range = 24°C - 18°C
Range = 6°C
So the range of the student's data set is 6°C.
