Suppose you have the following SLR model: Y = 106 + 25X + u Further suppose that the Zero Conditional Mean assumption holds and that the unconditional mean of X, denoted as x = 60. Calculate the unconditional mean of Y, denoted as y. Include a negative sign if necessary. Do NOT put a comma in answers. Hint: You will need to take advantage of the Law of Iterated Expectations to answer this question. The first step is to take a conditional expectation of something so that you can take advantage of the Law of Iterated Expectations.
