Labor Day HW

Yo yo yo! For the three day weekend I need you to complete all of the problems on the handout I provided in class Friday--EXCEPT NUMBER 20!

I know this is tough...try your best and we'll talk about it all Tuesday. However, don't give me a little "i didn't get it" and expect credit. This course is all about THINKING. So try your best, and you'll be aight.

And yes, I'm checking. Here's some help...

Number 21 asks you to investigate whether admissions decisions are independent of race/ethnicity. Well, if they are in fact indepdendent, we should see the same proportions of accepted students as in our total applicants. Think about it--if your ethnicity doesn't matter and 40% of our applicants are white, then we'd expect that same 40% to show in our accepted students.

So, here's how we start. First, we need to find the overall percentages of each group. What percent of everyone was Black/Hispanic? What percent of everyone was Asian? What percent of everyone was White? Calculate these three values.

Next, we want to look at only the accepted students. What percent of the accepted students where Black/Hispanic? What percent of accepted students where Asian? What percent of accepted students were white?

To conclude, we compare these values. If the overall proportions match up with the "accepted" proportions, then admissions decisions and race/ethnicity were independent.

Good luck!
