Choose the correct statement below: Question 3 options: Linear regression coefficients are chosen such that total sum of square is minimized, which is the total squared distance of the actual observations to the mean of y Linear regression coefficients are chosen such that regression sum of square is minimized, which measures the distance from the regression line to the mean of y. Linear regression coefficients are chosen such that residual sum of square is minimized, where residual or error term is measured by the difference between the actual and predicted value of y
