here is a real example with some categorical data
Consider the article (and data therein) on sleepy driving: (Connor et al. "Driver sleepiness and risk of serious injury to car occupants: population based case control study", British Medical Journal, 2002, https://www.bmj.com/content/bmj/324/7346/1125.1.full.pdf )
Although the researchers look at many variables, consider the two following two variables: (1) driver sleepiness score of 1-3 vs 4-7, (2) driver involved in an "injury crash" or not. Note that there seems to be some missing information with respect to the sleepiness score.
explanatory variable = sleepiness score
response variable = whether or not there was an "injury crash"
The data were selected based on the response variable, so it was a case-control study. Therefore, it is impossible to know the proportion (out of all crashes) of crashes that were "injury crashes."
(we could provide code / output) Using the infer syntax and the odds ratio, complete a full hypothesis test: state null and alternative hypotheses with parameter values,
(we could provide code / output) Using the infer syntax, find and interpret a 90% bootstrap percentile CI for the true OR.
