The middle 50% of scores are found within the IQR, which is 109. So, Q1 (39) minus half of the IQR (54.5) gives us the lower bound of 26.5. And, Q3 (148.5) minus half of the IQR (54.5) gives us the upper bound of 94. So, the middle 50% of scores are between 26.5 and 94, and choice B is the only option that includes these values.
