We went over most of this assignment in my first lab, and the WHOLE assignment in my second lab, so you should be well equipped for this!
For questions 8-13, Remember that marginal distributions deal with the MARGINS, so they are only total rows. (You'll notice you have to compute the total values by yourself).
Conditional distributions are based on one condition. Block out the row/column you are interested in. Remember, that will be the SPECIFIC. (For example "whether you buy or not" is not a specific since there are nonbuyers and buyers. "Higher" IS a specific, because it just isn't "quality").
Remember: Be careful with the word CAUSE. What does that mean? When can we conclude causation?
