Figure 2.

(A and B). The relationship between observed active-smoker proportion and occupancy rate in main smoking areas (low-stakes tables and slots). [(A) low-stakes smoking slots, and (B) low-stakes smoking tables. The proportion of active smokers, expressed as a percent, is calculated as 100 x observed active smokers divided by observed total people, and occupancy rate is calculated as 100 x observed total people divided by theoretical maximum capacity. Two separate visits to each casino are shown in the plots using matched plotting symbols. Results shown exclude the second visit to Casino F in which a very large occupancy was observed].
