Final answer:
The range between the lower bound of 249.5 and the upper bound of 250.5 is 1.
Step-by-step explanation:
The range between the lower bound of 249.5 and the upper bound of 250.5 is 1. The range is calculated by subtracting the lower bound from the upper bound. In this case, 250.5 - 249.5 = 1. Therefore, the range is 1.
