A multiple regression equation with two predictor variables is calculated for a set of scores. The estimated regression equation is = 100.1+23.461 - 39.8b2. What is when = 42 and x2 = 73? Solve using the Final Exam Workbook. 3988.3 O-1822.5 O 136.7 1500.4 For Question 1, we interpret the b coefficient as O an estimate of the change in y corresponding to the particular coefficient change in each independent variable. an estimate of the change in y corresponding to the change in the coefficient of determination. an estimate of the change in y corresponding to a one-unit change in a when all other independent variables are negative. an estimate of the change in y corresponding to a one-unit change in a when all other independent variables are held constant.
