Answer: A.

Explanation: On the scatter plot most of the points are grouped (clustered) in the region where price is about $5–$15 and number sold is about 10–20, so statement A correctly describes the cluster.

A graph (scatter plot) shows the relationship by plotting each paired observation (price, books sold) as a point. From the pattern of points you can see:
- clusters (many points in the same area),
- the direction of any association (points slanting up = positive association, slanting down = negative association),
- the strength of the relationship (tight line of points = strong, scattered = weak),
- and outliers (points far away from the rest).
