Let Xi be a continuous variable, and let Di be a binary variable. An example of an interaction term between two independent, continuous variables is: a. Yi = β0 + β1Xi + β2Di + β3(Xi × Di) + ui. b. Yi = β0 + β1X1i + β2X2i + ui. c. Yi = β0 + β1D1i + β2D2i + β3 (D1i × D2i) + ui. d. Yi = β0 + β1X1i + β2X2i + β3(X1i × D2i) + ui. e. All of the above. f. None of the above.

An ecologist models the interaction between the tree frog (P) and insect (N) populations of a small region of a rainforest using the Lotka-Volterra predator prey model. The insects are food for the tree frogs. The model has nullclines at N=0, N=500, P=0, and P=75. Suppose the small region of the rainforest currently has 800 insects and 50 tree frogs. In the short term, the model predicts the insect population will • and the tree frog population will At another point time, a researcher finds the region has 300 insects and 70 tree frogs. In the short term, the model predicts the insect population will * and the tree frog population will
