The PQ&R Café and Grocery is a chain of small grocery stores with restaurants. The locations are grouped by type of area—rural, urban, and suburban. PQ&R collected data from all 28 of its locations on the rate of restaurant visits among its customers and the rate of large purchases in the grocery section. The results are presented in the graph. The average (arithmetic mean) rates for each group as well as the chain-wide average are represented by the horizontal and vertical lines.
Use the drop-down menus to fill in the blanks in each of the following statements based on the information given by the graph.
Among urban locations, there is a correlation between the rate of large purchases and the rate of restaurant visits.
The range of the rate of restaurant visits is least for locations.

1. We are asked to fill in the blanks for 2 parts: "Among urban locations, there is a ___ correlation between the rate of large purchases and the rate of restaurant visits" and "The range of the rate of restaurant visits is least for ___ locations".
2. Part 1. Let's mark all the urban locations and draw an estimated trend line. When the rate of large purchases increases, the rate of restaurant visits decreases. So, there is a negative correlation between the two.
3. Part 2. The range of the rate of restaurant visits in an area is the distance between the projection of the least and largest points (from that area) on the y-axis. The smallest range is the smallest distance. If we try to draw this out, we can see that the distance for the urban areas is less than the suburban and rural areas. So, the range of the rate of restaurant visits is least in urban areas.
4. Our answer will be:
Among urban locations, there is a strongly negative correlation between the rate of large purchases and the rate of restaurant visits.
The range of the rate of restaurant visits is least for urban locations.
