Which one of the following statements best describes the algebraic representation of the fitted regression line?
(A)\hat{y}_t = \hat{\alpha} + \hat{\beta}x_t + \hat{u}_t (B)\hat{y}_t = \hat{\alpha} + \hat{\beta}x_t (C)\hat{y}_t = \hat{\alpha} + \hat{\beta}x_t + u_t (D)y_t = \hat{\alpha} + \hat{\beta}x_t + \hat{u}_t
B
