Only correct errors, Do not answer it. #### Texts: Imagine you need to evaluate the mean difference in wage. In this analysis, you ask yourself: are there differences in wage by insurance status? Estimate a model that helps you understand the mean difference in wage when people have insurance versus people without insurance. What model will you pick? 1) What is the value of the mean difference? Are people with insurance earning more money? 2) Is the mean difference explained by chance alone? How do you know?
