A phаrmаceuticаl cоmpany is investigating the blооd pressure lowering benefits of a new drug. The company randomly assigns individuals to receive either zero (a placebo), 5, 10, or 20 mg of the drug, and calls this variable ti, and then measures each participant’s systolic blood pressure, and calls this variable si. They then estimate the following regression model for the effect of the drug on blood pressure: (1) The company also gathered data on each participant’s weight (wi) and age (ai), two variables which typically influence blood pressure. Using this information, they estimate another regression model: (2) How will the estimate of change from equation (1) to equation (2)?
