Answer

Brief Explanations:

  • Survey a random sample of the firemen who currently work in the city: Firemen are not representative of all city residents. They have a specific interest (related to their job) and may not have the same views as the general population.
  • Survey every third person who walks into the local grocery store: This is a convenience sample. People who go to the grocery store at a particular time may not be representative of all city residents. For example, it may exclude those who shop online, are at work, or are home - bound.
  • Survey the last 100 residents listed in the telephone directory: This is a non - random and potentially biased sample. Telephone directories may be outdated, and some people may not be listed (e.g., those with unlisted numbers, those who only use cell phones not in the directory).
  • Survey a random sample of persons within each neighborhood: This is a stratified random sampling method. By sampling within each neighborhood, we can ensure that different parts of the city (with potentially different demographics and interests) are represented. This helps to get a more representative sample of the entire city's residents.

Answer:

Survey a random sample of persons within each neighborhood.
