1. In a multiple regression equation, two independent variables are considered, and the sample size is 30. The regression coefficients and the standard errors are as follows. b1 = 1.598 Sb1 = 0.85 b2 = -1.259 Sb2 = 0.6 Conduct a test of hypothesis to determine whether either independent variable has a coefficient equal to zero. Would you consider deleting either variable from the regression equation? Use the .05 significance level. (Round your answers to 3 decimal places. Negative amounts should be indicated by a minus sign.) H0: 1 = 0 H0: 2 = 0 H1: 1 0 H1: 2 0 H0 is rejected if t < -2.042 or t > 2.042 t for b1 coefficient = t for b2 coefficient = variable can (Click to select) be deleted. rev: 03_18_2016_QC_CS-46019
