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= 2.677 sb1= 0.56
b2= -0.880 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.© BrainMass Inc. brainmass.com March 4, 2021, 8:13 pm ad1c9bdddf
