The population model is given by salary = Betao + Beta1 age + Beta2gdegree + Beta3gdegree times age + u. The variable salary is measured in dollars, age is measured in years and degree is a dummy variable that takes the value of 1 if the person has a graduate degree and zero otherwise. The base group is individuals without a graduate degree. Which of the following is false? (a) Beta0 is the intercept for a individuals without a graduate degree. (b) We would expect Beta2 to be positive. (c) Beta 1 is the slope for a individuals with a graduate degree. (d) Beta3 is the difference in intercept between a individuals with and without graduate degrees. (e) Both (c) and (d)

Step 1
The given model is a linear regression model where salary is the dependent variable, and age and gdegree are independent variables. The model includes an interaction term between gdegree and age. Here's the breakdown: - Beta0: Intercept when age = 0 and gdegree = Show more…

Consider the following OLS regression line: wage = α0 + γ0male + β1educ + u, where wage measure individuals' hourly wage and educ the number of years of formal education. The variable male takes on the value one if the person is male and zero if the person is female. Which of the following statements is correct? a. The coefficient γ0 determines whether there is discrimination against women. b. The coefficient γ0 determines whether there is difference between the average wage earned by women compared to the average wage earned by men. c. The coefficient γ0 determines whether there is difference between the average wage earned by men compared to the average wage earned by women. d. Both a and b.
