5. Which of the following statements is true?
(A) In a simple regression model, the determinant is zero means there is no relation between thedependent and independent variables.
(B) If the distribution of the disturbance term is not a normal distribution, then the OLS estimatorcannot be unbias.
(C) If the intercept of the regression function is very close to zero, we can infer that the intercept isnot significantly different from zero.
(D) If we use t-distribution to test whether the coefficient of the regression function is significantlydifferently from zero, the distribution of the OLS estimator of the coefficient should be a normaldistribution.
