Question

the government of a large city needs to determine whether the citys residents will support the removal of the citys university. 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 students and employees of the university. 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:

• Sampling students and employees of the university only focuses on a specific group related to the university, not all city residents.
• Sampling people at a local night - club is a convenience sample and may not represent all city residents (e.g., some residents may not go to night - clubs).
• Sampling the last 100 residents in the telephone directory may be a non - random and potentially biased sample (e.g., not all residents may be listed, or the listing order may not be random).
• Sampling a random sample of persons within each neighborhood is a form of stratified sampling (if neighborhoods are considered as strata). It helps to ensure that different parts of the city (different neighborhoods) are represented, increasing the likelihood of getting a sample that is representative of the entire city's residents.

Answer:

Survey a random sample of persons within each neighborhood.
