A and E are the correct statements.
A is correct because the population includes all residents of the subdivision, as they are the group that the association would like to know about.
E is correct because "82% of the residents are in favor" is a sample statistic, as it applies only to the 45 surveys that were randomly selected and not to the entire population.
