Suppose that the relationship between 2 random variables, \( Y \) and \( X \), is given by the following Simple Linear Regression Model: \[ Y=50-18 X+u \] Suppose further that the Zero Conditional Mean Assumption holds and that the unconditional mean of \( X, \mu_{X} \), is equal to 2 . Calculate the unconditional mean of \( Y, \mu_{Y} \). Hint: Remember the properties of the Population Regression Function and the Law of Iterated Expectations.
