timeliness of flights

A study was done on the timeliness of flights (on-time vs. 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 delayed flights). However, in each of the five cities separately, AirMedian does better.

Which of the following is correct?

  1. (a) This situation is mathematically impossible.

  2. (b) This is an example of Simpson''s Paradox.

  3. (c) ""City"" is a lurking variable in this example.

  4. (d) This is an example of a negative association between variables.

  5. (e) Both (b) and (c) are correct.
