Consider a linear regression model where y represents the response variable, d1 is a dummy variable assuming values of 0 or 1, and d2 is another dummy variable assuming values of 0 or 1. The model is estimated as y = 160 + 15d1 + 32d2.
a. Compute y for d1 = 1 and d2 = 1.
b. Compute y for d1 = 0 and d2 = 0.
