Round to the nearest whole number. b) Which of the following best interprets the regression coefficient for Age? O For each additional productivity unit, age on average increases by 1.648 assuming wage is held constant. For each additional dollar in wage, age increases by 1.648, on average, assuming productivity is held constant. O For each additional year in age, wage on average decreases by -0.983 assuming productivity is held constant. For each additional year in age, productivity units on average increase by 1.648 assuming wage is held constant
