Question

the government of a large city needs to determine whether the citys residents will support the repair of several roads. 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 the residents who use public transportation survey every fourth person to go to the local night club. survey the last 100 residents listed in the telephone directory survey a random sample of persons within each neighborhood

Explanation:

• Option 1: Surveying only residents who use public transportation would exclude those who don't, leading to a biased sample.
• Option 2: Surveying people at a local night club would only target a specific subset of the population (likely younger, more social individuals), not representing all residents.
• Option 3: Surveying the last 100 residents in the telephone directory is arbitrary and may not be a random or representative sample (e.g., some people may not be listed, or the directory may be outdated).
• Option 4: Surveying a random sample of persons within each neighborhood ensures that all areas (and thus a diverse range of residents) are included. This helps in getting a more representative sample of the entire city's population.

Answer:

Survey a random sample of persons within each neighborhood.
