a. What is a residual?
O A. A residual is a point that has a strong effect on the regression equation.
O B. Aresidual is the amount that one variable changes when the other variable changes by exactly one unit.
O C. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
O D. A residual is a value that is determined exactly, without any error.
