Consider the following population linear regression model: Y; = a + 5X1: + 51'. 1. [5 points] Explain in words (i) what it means that 130158 is an unbiased estimator, and (ii) the dierence between an unbiased estimator and a consistent estimator. Is it related to the sampling distribution of 501,3? Explain your answer. 3. [5 points] Can you explain ALL the assumptions we used to show that [30,53 is a consistent estimator. Describe why we needed the assumption to derive the result. Pick one and explain how you would show that the assumption holds in your setting
