Given the Regression Model Y = β₀ + β₁X₁

Given the regression model y = β₀ + β₁X₁ + β₂X₂ + ε,if we are testing the significance of the independent variable X₁ and we reject the null hypothesis H₀: β₁= 0,we conclude that:

A) X₁is significantly related to y in this model.
B) X₁is not significantly related to y in this model.
C) β₁is not significantly related to y in this model.
D) β₁is significantly related to y in this model.
E) the error term assumptions have been satisfied.
