A city law requires all buildings to have a fire safety inspection at least once every three years. Concerned that some of these inspections are not being done, the mayor orders a survey to see what fraction of the city's buildings may be out of compliance. Results for the sample appear in the table below.

For which of the building classifications could you use our methods of inference to create 95% confidence intervals for the proportion of buildings lacking the required inspection?
