Consider the given situation and the statistical summary and answer the following questions. Ecologists sometimes find rather strange relationships in our environment. One study seems to show that beavers bene fit beetles. The researchers laid out 23 circular plots each four meters in diameter, in an area where beavers were cutting down cottonwood trees. In each plot they counted the number (x) of stumps from trees cut by beavers and the number (y) of clusters of beetle larvae. Some descriptive...
