Question: Identify the population. Choose the correct answer below.

Option 1: 'The population is the​ 57% of adults who support smoking bans.' This describes a specific subgroup (those who support smoking bans) and a particular statistic, not the entire population of interest. It represents a sample results or a conditional group, not the full population.

Option 2: 'The population is adults in the United States.' This defines the population as the entire group of interest when studying attitudes or behaviors among adults in the U.S. It excludes non-adults and excludes people outside the United States, aligning with a clearly defined target population for many social surveys.

Option 3: 'The population is adults in the United States who support smoking bans.' This is a subset of the population (a specific characteristic: support for smoking bans) and would be considered a sample or a defined group within the population, not the full population itself.

Option 4: 'The population is the 1021 adults surveyed.' This describes the sample size and, more precisely, the sample, not the population. The population is the larger group from which the sample is drawn, not the individuals actually surveyed.

Option 5: 'The population is adults.' This is overly general and lacks a defined scope. Population should specify the geographical location (e.g., in the United States) to be meaningful for a study about smoking bans within a country, unless the study explicitly covers all adults globally.

Option 6: 'The population is people in the United States.' This is close, but it may include non-adults if taken literally as 'people' rather than 'adults.' If the study focuses on adult attitudes, this option is too broad. When the target is specifically adults, the more precise phrasing is 'adults in the United States.'

Overall, the option that most precisely and appropriately defines the population for a study about adult attitudes in a specific national context is the one that states: 'The population is adults in the United States.' This matches the standard concept of population as the complete set of individuals about whom inferences are to be made, within the defined scope of the study.
