1) lowa City is the home of the university of Iowa. Do schools in lowa City out perform the rest? Answer, and provide the test to support your answer.

2) Test scores are meant to reflect the success of a school's academic program. But many critics point out that factors other than academic success can influence a score. In particular, a school's score might be merely a reflection of the wealth of the student body. Address this issue by fitting a regression line to predict school test score from poverty score. Is there evidence that poverty is associated with the test score?

3) Interpret each of the first three of four diagnostic plots that R provides for this model. (The residual plots, the normal q-q plot, and the scale-location plot.)

4) Which point has the highest leverage? (Indicate which row it belongs to in the data frame.) Are there any bad leverage points? If so, which? If not, show R code you used that verifies that there are no bad leverage points.

5) What hypotheses (null and alternative) is the F-test in the summary output for Question 2 testing? Give the conclusion to this test.
