Estimate the model using the OLS method.

Use a t-test with the critical value method and a significance level of 5% to test H₀:₃+₁=0 against H1:₃+₁>0.

Show all your working. Your answer should include the relevant output for the estimated regression model. Also, you should state the null and alternative hypotheses, the significance level, the formula for the test statistic, the PDF of the test statistic under the null hypothesis, the value of the test statistic, the critical value and your conclusion.
