1 Understanding the Simple Linear Regression Model Assume the following model: 12- = 10.0 + 0.5X1- + 61', e2- i451 Mo, 1) (a) IE)[Y|X = 0] = ?, ]E[Y|X = 1]= ?, var[Y|X] = ? (b) What is the probability of Y > 10, given X = 2 ? (c) If X has a mean of zero and variance of 20, What are IE}[Y] and Var(Y)? (d) What is Cov(X, Y)
