Answer:
B
Explanation:
Since the Inter-quartile range is the range of the values of Q3 and Q1, or the ends of the boxes, then you know that Fitness Plus has a smaller inter-quartile range than the Fitness Center. For the Fitness Center, you do 22-15 to get 7 and for Fitness Plus, you do 20-14 to get 6, and 6<7, therefore B being the correct answer.
