Dr. Greg Garman, Director of the VCU Rice Rivers Center, has studied Atlantic Sturgeon extensively during his career. Suppose that he has determined a linear model that can be used to predict the weight of an Atlantic Sturgeon based upon its length: y = a + bixi. Upon further study, Dr. Garman has noticed that the relationship between weight and length for these fish is different for males than for females. Thus, he'd like to modify his linear model to be able to fully take into account the sex of the fish. Please list the complete modified model that will fully take into account the sex of the fish, and then be sure to explain each of the terms of the new model (including all terms from the original model and any new terms added to modify the model). Original Model: y = a + bx Description of original terms: : XI: a: bi: New Model: y = a + bixi + Description of new terms:
