Question 1: Intent β to β Quit Smoking. On December 2019, this study surveyed at random 1000 smokers about their intentions to quit smoking. The survey results showed that 25% of the surveyed smokers plan to quit smoking on January 1, 2020 (E1). As a follow-up, the same 1000 persons were surveyed on January 10, 2020 to see whether they did quit smoking. The follow-up survey showed that 30% of them actually quitted smoking (E2). Furthermore, the study showed that 80% of those smokers who planned to quit smoking actually quit smoking.
E1 = Planned to quit smoking and E2 = Actually quit smoking
