A study was done on the timeliness of flights categorized as either "on time" or "delayed" of two major airlines: StatsAir and AirMedian. Data were collected over a period of time from five major cities and it was found that StatsAir does better overall (i.e., has a smaller percentage of flights categorized as delayed). However, in each of the five cities separately, AirMedian does better (i.e., has a smaller percentage of flights categorized as delayed in each city). Which of the following is correct? Check all that apply. A. This is an example of Simpson's paradox. B. "City" is a lurking variable in this example. C. This is an example of a negative association between variables.
