Recall the shoe size estimation from the regression lecture. The model estimation was given by the equation below. If we remove Sex as a predictor, what will happen to R-Square and adjusted R-Square? Shoe_Size  = -1.774 +.34465 Age +.0303 Weight +.7919 Sex + 0.0039 IQ_SCORE  

When we run a regression, we get the coefficient estimates. We can also get the predicted values and the residuals. Furthermore, we can conclude that the average of the residuals is equal to:
