Train = the number of weeks of training,
Gender = the gender of an individual;1 for males,and 0 for females.
Excel partial outputs corresponding to these models are available and shown below.
Model A: Salary = β₀ + β₁ Educ + β₂ Exper + β₃ Train + β₄ Gender + ε Model B: Salary = β₀ + β₁ Educ + β₂ Exper + β₃ Gender + ε A group of female managers considers a discrimination lawsuit if on average their salaries can be statistically proven to be lower by more than $500 than the salaries of their male peers with the same level of education and experience.Using Model B,what is the alternative hypothesis for testing the lawsuit condition?

A) H_A: β₃ ≤ 500
B) H_A: β₃< 500
C) H_A: β₃ ≠ 500
D) H_A: β₃ > 500
