Question:

The following estimated regression equation was developed for a model involving two independent variables.

After x2 was dropped from the model, the least squares method was used to obtain an estimated regression equation involving only x1 as an independent variable.

a. Give an interpretation of the coefficient of x1 in both models.

b. Could multicollinearity explain why the coefficient of x1 differs in the two models? If so, how?
