Please help to solve this. 

### Problem 5 **Consider the equation \( Y = \beta_0 + \beta_1X_1 + \beta_2X_2 \), where \( X_1 \sim (\mu_{X_1}, \sigma^2_{X_1}) \) is independent of \( X_2 \sim (\mu_{X_2}, \sigma^2_{X_2}) \). With this information, answer the following questions:** **(a)** What is the expected value of \(X_1\)? What is the expected value of \(X_2\)? **(b)** What is the variance of \(X_1\)? What is the variance of \(X_2\)? **(c)** What is the expected value of \(Y\)? **(d)** What is the variance of \(Y\)? **(e)** What is the marginal effect of \(X_1\) on \(Y\)? What is the marginal effect of \(X_2\) on \(Y\)?
