Answer: Choice A.
Three fourths of the fish he caught were larger than 22 pounds.
==============================================================
Explanation:
The 1st quartile (Q1) is visually located at the left edge of the box. From the diagram, it's not clear where that left edge is exactly. However, 22 seems to be the closest of the answer choices because the left edge appears to be between 20 and 30.
1/4 of the population is below Q1 while the remaining 3/4 is above this marker.
If Q1 = 22, then statement A saying "Three fourths of the fish he caught were larger than 22 pounds" is correct.
