The following computer output shows an estimated equation. Here; W: Weekly wage.
MALE: Gender, takes the value of 1 if the worker is male and 0 if female.
EDU: Education Level,
EDU1=1 if the worker has no formal education and 0 otherwise,
EDU2=1 if the worker has primary education and 0 otherwise,
EDU3=1 if the workerhas secondary and high school degree and 0 otherwise,
EDU4=1 if the worker hasbachelor, master, and/or Ph.D. degree and 0 otherwise.
EXP: Experience (thenumber of years being employed).
Dependent Variable: W
Method: Least Squares

a)
From the given output the estimated wag model is given as
Weekly wage = 508.8 + 486.3 Male + 37.9 (EDU32) + 154.0 (EDU3) + 251.2 (EDU4) + 10.3 (EXP)
b)
Significance test for variable EXP
Hypothesis:
H 0 : β E x p = 0 H 1 : β E x p 0
From the output p-value=0.0001
Decision rule:
If the p-value is greater than the significance level, there is no evidence to reject the null hypothesis.
If the p-value is lesser than the significance level, the hypothesis is rejected.
Conclusion:
The p-value (0.0001) is less than the significance (0.05)
Thus, the null hypothesis is rejected.
There is a relation between the experience of the worker and the weekly wages.
Thus, the variable Exp is significant at a 5% level of significance.
Significance test for variable EDU2
Hypothesis:
H 0 : β E d u 2 = 0 H 1 : β E d u 2 0
From the output p-value=0.2868
Decision rule:
If the p-value is greater than the significance level, there is no evidence to reject the null hypothesis.
If the p-value is lesser than the significance level, the hypothesis is rejected.
Conclusion:
The p-value (0.2868) is greater than the significance (0.05)
Thus, there is no evidence to reject the null hypothesis.
There is no relation between the primary education of the worker and the weekly wages.
Thus, the variable EDU2 is not significant at a 5% level of significance.
c)
From the given output coefficient of determination R-squared = 0.461610.
This means that 46% variation in the dependent variable is explained by the independent variable.
46% of the data fit the regression model.
The strength of the relationship of the model is 46%

d)
The coefficient of the male is 486.2831
The positive regression coefficient means that after considering all other variables male have 486.2831 more weekly wages than the female.
The coefficient of the EDU3 is 153.9977
The positive regression coefficient means that after considering all other variables the worker who has a secondary and high school degree has 486.2831 more weekly wages than the others.
The coefficient of the EXP is 10.28997
This means that for every unit change in the experience of the worker the mean change in the weekly wages of the worker is 10.28997.
The positive coefficient implies that there is a positive correlation between the experience of the worker and the weekly wages of the worker. This means that if the experience of the worker increases the wages of the worker also increases
