Consider the single Linear Regression Model:

Y = βX + U

without an intercept (β is a scalar constant; X is a scalar random variable). Imagine that you have taken a random sample from this population. If you estimate a regression using OLS, but you do not include an intercept, do you know if the mean of the residuals is zero? Explain.
