Question 1 - Run a regression of Y on x₁, x₂ and x₃ and answer the following questions.

i) State the fitted regression model.

ii) Conduct a hypothesis test that X₂ is positively related to Y.

iii) Test the hypothesis H = β = β = β = β = 0 against the hypothesis that at least one coefficient is non-zero.

Question 2 - Run a regression of Y on x₁, x₂, x₃, x₄ and answer the following questions.

i) Compare and contrast the standard errors on the estimates of β₃ from both regressions.

ii) Compare the fit of the two models using an appropriate measure of model fit.

Question 3 - Plot the standardized residuals from the regression in question 2 above against the fitted values and use these to answer the following questions.
