Consider the regression equation lnY^1=4.48+0.4X11+0.7X2. a. Predict the value of Y when X1=8.3 and X2=4.6. b. Interpret the meaning of the regression coefficients 100b1, and 100b2. a. The predicted value of Y is (Type an integer or decimal rounded to two decimal places as needed.) b. Choose the correct answer below. A. Holding constant the other variables, for every one percent increase in X1 or X2, the value of Y increases by b1 or b2 units, respectively. B. Holding constant the other variables, for every one unit increase in X1 or X2, the value of Y increases by b1 or b2 percent, respectively. c. Holding constant the other variables, for every one percent increase in X1 or X2, the value of Y increases by b1 or b2 percent, respectively. D. For every decrease of one unit of In Y, holding b0 constant, the estimated change in X1 or X2 is 100b1 or 100b2 units, respectively. E. Holding constant the other variables, for every one unit increase in X1 or X2, the value of Y increases by 100b1 or 100b2 percent, respectively
