Problem 3: Generate a covariate matrix X of dimension n x k, where n - 250 and k 4. The first column in X should be a column of ones and the other three columns can be generated from a relatively diffuse normal or uniform distribution. Let B (0.5, 0.75, 1, 1.25 )' and let o - 1. Discuss how you would test the following four null hypotheses: (a) Ho : B2 - 0. (b) Ho : Ba - 1, (c) Ho : 82 - B4 - 0, and (d) Ho : B3 - B4 - 0. Perform these tests and report your results in a Table
