Consider an experiment using birds in which we will use a simple ANCOVA to examine the effects of seed type (low calorie vs. high calorie) and amount of salt eaten (measured by changes in the mass of a salt stick) on feather stiffness. Which of the following is a representation of the model we will use to analyze the data?
