Using the 526 observations on workers in a certain dataset, we include educ (years of education), exper (years of labor market experience) and tenure (years with the current employer) in regression explaining log(wage) (logarithm of workers' average hourly earnings): In(wage) = Po + Beduc + Bexper+B3tenure + u. (1) Part of the EVIEWS estimation output is given below: Dependent Variable: LOG(WAGE) Method: Least Squares Date: 10/16/14 Time: 10:32 Sample: 1 526 Included observations: 526 Variable EDUC EXPER TENURE R-squared Adjusted R-squared S.E. of regression Sum squared resid Log likelihood F-statistic Prob(F-statistic) Table 2 Coefficient Std.

Use a 2- sided alternative for the intercept and 1-sided alternatives for the regressors' coefficients. (12 marks) (b) Provide interpretation of the coefficients of model where possible. (5 marks) (c) Using information from Table 2 test the overall significance of the model at the 5% significance level. Would your answer change if the significance changes to 10%? level of the test (6 marks)
