Question

the government of a large city needs to determine whether the citys residents will support the building of a new middle school. the government decides to conduct a survey of a sample of the citys residents. which one of the following procedures would be the most appropriate for obtaining a sample of the citys residents? survey a random sample of adults who currently have children in public schools. survey every tenth person to use the public restroom. survey the last 100 residents listed in the telephone directory. survey a random sample of persons within each neighborhood

Explanation:

• Surveying a random sample of adults with children in public schools (first option) is biased as it only focuses on a specific group related to schools.
• Surveying every tenth person using the public restroom (second option) is a convenience sample and may not represent all city residents.
• Surveying the last 100 residents in the telephone directory (third option) is also a non - random and potentially biased sample.
• Surveying a random sample of persons within each neighborhood (fourth option) uses stratified sampling (by neighborhood) which helps in getting a more representative sample of the entire city's residents.

Answer:

Survey a random sample of persons within each neighborhood.
