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 fifth person to enter the local church on sunday. survey the last 100 residents listed in the telephone directory. survey a random sample of persons within each geographical region of the city

Explanation:

• Sampling residents who use public transportation only targets one specific group and may not represent all residents.
• Sampling people at a church on Sunday excludes those who don't attend church and may not be representative.
• Sampling the last 100 in a telephone directory may have biases (e.g., not all have landlines, listing order may not be random).
• Sampling a random sample within each geographical region (stratified sampling) helps ensure representation from all parts of the city.

Answer:

Survey a random sample of persons within each geographical region of the city.
