A study оf the fifty species оf оаk trees in the United Stаtes exаmined the size of their acorns, measured in cubic centimeters, and the geographic range they inhabit, measured in square kilometers. The researchers wanted to examine whether oak tree species with bigger acorns tend to have larger geographic ranges. One possible explanation is that larger acorns may be spread by larger animals, and larger animals may move across larger areas. For the species of oak trees that live in the eastern United States, the following regression equation was used: where acorn size is measured in cubic centimeters and range is measured in square kilometers. One eastern oak species has an acorn size of 3.8 cubic centimeters. A newly identified eastern oak species has an acorn size of 12.6 cubic centimeters, which is larger than the acorn sizes shown in the scatterplot used to create the regression equation. In a short paragraph, explain how the regression equation can and cannot be used in this situation. Your answer should address both of the following: What the regression equation predicts for the species with a 3.8 cubic centimeter acorn. Why the regression equation should not be used to predict the range for the species with a 12.6 cubic centimeter acorn
