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.
This solution contains a step by step method for computing test statistics for testing equality of regression coefficients. The answer is provided in an attached Word file.
