If the hypothesis H₀: β₁ = 0 is rejected,then the sample regression coefficient b₁ indicates the change in the predicted value for a unit change in X₁ when all other X_i variables are held constant.

Question

Quizplus · Accepted Answer

When the null hypothesis is rejected, it means that the slope coefficient for X₁ is statistically significant and different from 0. The sample regression coefficient (b₁) then represents the estimated change in the predicted value of the response variable for a unit change in X₁ while holding all other variables constant.
