Variable from the regression equation

Assignment Help Basic Statistics
Reference no: EM132412472

In a multiple regression analysis, two independent variables are considered, and the sample size is 25. The regression coefficients and the standard errors are as follows.

b1 = 2.676Sb1 = 0.56b2 = -0.880Sb2 = 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 0.05 significance level. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)

H0: β1 = 0H0: β2 = 0 H1: β1 ≠ 0H1: β2 ≠ 0 H0 is rejected if t < -2.074 or t > 2.074
