Question One:
We are curious about Facebook use on Penn State Campus. Here are some numbers collected about two different places to live on campus. Note these are different groups--a person who counts for once a day is not included in the once a week data. In addition, we were only interested in people who used facebook, not non-users.:
3) What percent of University Park users say they use facebook at least once a week?
4) What percent of people who use facebook once a day are on the Commonwealth campus?
5) Find the expected values for each of these cells.
6) Find the chi-squared values for each of these cells. Which one is the largest? What does that mean? Which one is the smallest? What does that mean?
7) Find the sum of the chi-squared values.
8) Is there a difference between facebook users on one campus as opposed to the other? Explain how you know.
Head on over to this weeks Data Set! Enjoy! :)
