The OLS estimators of the coefficients in multiple regression will have omitted variable bias: A K 7 1' a. only if an omitted determinant of Yr. is a continuous variable. A '~ 7 3 b' if an omitted varible is correlated with at least one of the regressors, even though it is not a determinannt of the dependent variable. A K 7 1' c. only if the omitted variable is not normally distributed. A \" 7 3 d' if an omitted determinant of Y,- is correlated with at least one of the regressors. A \" - 3 e. if the degree of freedom is less than 50
