The sample space is the set of all possible outcomes of a statistical study or experiment. In this case, the researcher is visiting the entire population of 1,200 local residents, so the sample space is equal to the population of 1,200 local residents. It is not equal to the number of residents who support the new smoking ban (as this is only one possible outcome), the number of local residents who smoke (which is not necessarily related to the research question), or unknown (as we have sufficient information to define the sample space).
