In a multiple regression equation two independent variables are considered, and the sample size is 24. The regression coefficients and the standard errors are as follows: b2 = 2.578 b = -0.550 Sbi Sb = 0.35 = 0.84 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 0.05 significance level. (Round the final answers to 3 decimal places. Negative answer should be indicated by a minus sign.) Ho: B1 = 0 Ho: B2 = 0 H: B1 #0 H: B2 #0 Ho is rejected if t < -2.080 or t> 2.080. t = (Click to select) 2 variable can be deleted.
