Figure 5 shows a scatterplot for the variables number of farms and mean farm size in the United States. Each dot represents data from a single year between 1950 and 2000; on this diagram, the earlier years generally are on the right and the later years on the left. Estimate the correlation coefficient by comparing this diagram to those in Figure 3 and discuss the underlying reasons for the correlation.
