Linear regression
Hello
What does it mean that the residuals in linear regression is
normal distributed? Why is it only the residuals that is, and not
the "raw" data? And why do we want our residuals to be normal?

8. Linear equations and the regression line
Suppose a graduate student does a survey of undergraduate study
habits on his university campus. He collects data on students who
are in different years in college by asking them how many hours of
course work they do for each class in a typical week. A sample of
four students provides the following data on year in college and
hours of course work per class:
Student
Year in College
Course Work Hours per...

Draw a scatterplot with a linear regression line for which the
condition E(ui|Xi)=0 does not hold for all Xi, but E(ui)=0. Be sure
to explain how your scatterplot satisfies these criteria.
