This is a stata beginner level homework on an introduction to linear regression using stata. The answers need to be detailed for both graphs and interpretations.

In order to do this homework you will need to download the stata file by going on this link: http://www.stata-press.com/data/acock3.html and selecting the file "agir3".

Under the file agir3 you will find GSS2006_chapter8.data mentioned in the homework.

1. Use gss2006_chapter8.dta. Imagine that you heard somebody say that there was no reason to provide more educational opportunities for women because so many of them just stay at home anyway. You have a variable measuring education, educ, and a variable measuring hours worked in the last week, hrs1. Do a correlation and regression of hours worked in the last week on years of education. Then do this separately for women and for men. Interpret the correlation and the slope for the overall sample and then for women and for men separately. Is there an element of truth to what you heard?

2. Use gas2006_chapter8 dta. What is the relationship between the hours a person works and the hours his or her spouse works? Do this for women and for men separately. Compute the correlation the regression results and the scattergrams. Interpret each of these. Next test if the correlation is statistically significant and interpret the results.
