Solve the problem below

2. [10 pt) A linear regression with intercept 60 = 0 is going to be t to a set of data consisting of two points (regression through the origin). Specically, the model under consideration is Y5 = 291333- +5171 3': 1:2- (1) where 51- are iid. N (0, 0'2). You are going to use ~ _ Y1 Y2 as an estimator of the slope. (a) Evaluate the mean and variance of 51. Make sure you Show your work. (b) Is 51 an unbiased estimator of 51? Explain
