Question: In the simple linear regression model, use the normal equations (the first order conditions of minimizing the sum of squared errors) to prove that b

In the simple linear regression model, use the normal equations (the first order conditions of minimizing the sum of squared errors) to prove that b = (xi - )(yi -)/(xi - )2 . You can use the notation above as you type your answer. Notice that used an "x" with 2 dots on top to stand for Xbar
