Which of the following is the Z score multiple regression formula with two predictor variables? a. Predicted Z_Y = (Beta_1/Z_X1) + (Beta_2/Z_X2) b. Predicted Z_Y = (Beta_1/[Z_X1 + Z_X2]) + (Beta_2/[Z_X1 + Z_X2]). c. Predicted Z_Y = (Beta_1) (Z_X1) + (Beta2) (Z_X2) d. Predicted Z_Y = (Beta1/Beta2) + (Z_X1/Z_X2). In a contingency table, the word "independence" means a. the distribution of one variable varies over different levels of the other. b. the variables in the table should not be compared. c. the observed frequencies are larger than the expected frequencies. d. there is no relationship between the variables.
