In the regression model Y_i= ₀+ ₁X_i + ₂D_i+ ₃(X_i D_i) + u_i, where Y is the dependent variable (for example, hourly wage), X is a continuous variable (for example, education) and D is a binary variable (for example, for gender (i.e. female)), to test that the two regressions are identical (for example, women and men have the same hourly wages), you must use the:

A) t-statistic separately for ₂= 0, ₃ = 0.

B) F-statistic for the joint hypothesis that ₀ = 0, ₁ = 0.

C) t-statistic separately for ₃ = 0.

D) F-statistic for the joint hypothesis that ₂ = 0, ₃= 0.
