# Confidence interval estimation for regression coefficients

1 What is the R^2 Value for your regression equation?

2 What is the value of the coefficient of Blue Collar in your equation?

3 What is the lower limit of the 95% CI for this coefficient?

4 What is the upper limit of the 95% CI for this coefficient?

5 Interpret the 95% confidence interval for the B1 parameter

6 What is the p-value for your ANOVA test?

7 Interpret your ANOVA table - does the explanatory variable provide

8 Interpret your ANOVA table - does the explanatory variable provide

at least some power in estimating the dependent variable?

9 What is the relationship between the t-ratio for the estimated

coefficient of the explanatory variable and the F-ratio in the ANOVA

section of the output?

10 Do these two test statistic values provide the same indication

regarding a possiible relationship between yearly changes in the

wages and salaries of white-collar and blue-collar workers?

Explain why or why not.
