Imagine conducting a survey experiment. Respondents are shown get-out-the-vote ads (x) that have a message about civic duty (treatment #1), a message about social pressure (treatment #2), or just information about how to vote (control). Respondents are then asked whether they intend to vote in the upcoming election (y)

a. Draw the structure of the dataset. b. Describe how the variables would be coded. c. Add some "hypothetical" cases to the dataset you drew. d. Explain what kind of bivariate hypothesis test you would use to analyze the association between x and y.
