Final answer:
The range is derived by subtracting the smallest value from the largest value in a dataset. Without specific data, it's not possible to give an exact range, but based on given intervals, option B) 4 is a potential answer.
Step-by-step explanation:
The range of the data is calculated by subtracting the smallest value in the set from the largest value. To find the range, you need to locate these two values and then complete the subtraction. In this case, if we refer to the information provided, the range mentioned for one dataset is from 0.5 to 1.5, which gives a range of 1 (1.5-0.5 = 1). Similarly, other specified ranges are each 1 unit apart when you subtract the smaller number from the larger number within the given intervals. Without the specific dataset to refer to, we can say that the range is likely the difference between the smallest and largest numbers in the set, but without those exact numbers, one can't give a definitive answer. However, option B) 4 is a possible answer given ranges provided in intervals of 1 unit and central points increasing by 1.
