Suppose a sample regression equation is given by Yhat =3 0.40\deg x.
Suppose when X is 10,Y is observed to be 8.
What is the residual of the model prediction and does the model under or overpredict the value of Y ?
â—» =-1, the model overpredicts y
â—» -1 , the model underpredicts y
â—» =1, the model overpredicts y
â—» -1 , the model underpredicts y
