Answer: The correct answer is option D, "The range of each set cannot be compared."
Step-by-step explanation:
From the given dot plots, it can be observed that the range of Set 1 is from 1 to 9 and the range of Set 2 is from 2 to 10. Therefore, the statement "The range of Set 1 is less than the range of Set 2" is false. On the other hand, the statement "The range of Set 1 is greater than the range of Set 2" is also false.
