Please only answer question (e) (f), I'll like yr answer. Thanks!

Suppose you are regressing the unemployment rate (%) in country i E {1, 2, ..., 100} on the federal fiscal stimulus package that country received in 2011 (in $): UR; = 1 + 1S; + i You find that o = 0.21 with a with a (heterosckedascity robust) SE of 0.03 and 1 = -0.003 with a (heterosckedascity robust) SE of 0.03. (a) (4 points) What are the economic interpretations of Bo, ? (b) (6 points) Can you reject the hypothesis that the intercept is equal to zero at the 95% level? What is the economic interpretation of this test and its result? Does it make more sense to perform a one-sided hypothesis test or a two-sided one? (c) (6 points) Can you reject the hypothesis that Bo 0.15 at the 95% level? What about at the 99% level? Recall 20.005 2.58. (d) (4 points) Suppose you are asked whether the federal fiscal stimulus is effective in re- ducing the unemployment rate. How would you design a hypothesis test (say, at a 95% level) to answer this question? What would be your conclusion? (e) (5 points) Suppose you find out that you have an omitted variable problem, i.e., the true regression is U Ri + Qo + Qi Si + 22Z; + w! Zi is investment of i in 2010. Also suppose that a2
