Statement of a problem № m537


In a multiple regression equation, two independent variables are considered, and the sample size is 25. The regression coefficients and the standard errors are as follows. b1 = 2.676 sb1 = 0.56 b2 = 20.880 sb2 = 0.71 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.
