Suppose that a researcher considers the following regression model, (1) INC; = Po + By GEN; +82MARRIED; +ByAGE; + 6, where INC is individual is annual income ($/year), AGE; is i's age, and GEN; and MARRIED; are dummy variables representing, respectively, I's gender (GEN; - 1 ifi is male and 0 if female] and marital status (MARRIED; = 1 if / is married, and 0 if not married). Please answer question below with respect to model 1 above Question 4 1 points Save Answer In reference to model (1], if the researcher wants to test the hypothesis that both p and 82 are zero at 59% significance level, which of the following critical value should he use (when the model is estimated with a sample of 145 workers)? O a. F.INV. RT (0.05, 4,143) = 2.435 O b. F.INV.RT(0.05, 4, 141) = 2.436 O C. F.INV.RT (0.05, 2,143) = 3.059 O d. F.INV.RT[0.05,2,141] - 3.060
