A grоup оf reseаrchers cоnducted а cаse-control study to investigate if distances to a chemical factory (C point on the map below) associate with lung cancer in a neighborhood. They identified 20 cases (solid dots) from local hospital death certificates, and randomly selected 30 controls (open dots) without lung cancer. In order to examine the effects of distance, they drew three buffers that are 1 mile, 2 miles, 3 miles away from the factory, respectively (dash-line circles). Figure 1. Distances to a chemical factory Based on Figure 1, fill out the case-control table below. Using the table icon in the toolbar below (under the bold icon), recreate Table 5 and fill in your values.
