GRETL TASK - Linear Regression

GRETL TASK - Linear Regression
Using GRETL
Q1.Estimate the linear regression WAGE= β1 + β2 EDUC +e
Test the null hypothesis that β2 = 0 against the alternative that β2 > 0 at the 1% significance level.
Enter the value of the test statistic in the box (2dp)
Enter the critical value in the box (2dp): 
Enter the p-value of the test statistic (2dp)
Would you reject the null hypothesis at 1% significance level for this question above?
Q2.What is the expected wage for a person who has 15 years of education? (3dp)
What is the 99% prediction interval for a person who 15 years of education?
The lower bound (3dp)
The upper bound (3dp)
Q3Test the null hypothesis that β2 = 2 against the alternative that β2 < 2 at the 5% significance level.
Enter the value of the test statistic in the box (3dp)
Enter the critical value in the box (3dp)
Q4.Using the estimated model in Question 1, construct a 90% confidence interval for β2 . 
In the box below enter the value of the lower limit of the confidence interval (rounded to 4 decimal places).
In the box below, enter the value of the upper limit of the confidence interval (rounded to 4 decimal places).
