Question

at the beginning of a call to the cable company, a message tells customers, after you finish talking to our customer service representative, you will be asked to take a five - question survey about the level of service you received. it would be appreciated if you could please stay on the line to answer the survey questions. what type of sampling is the cable company using?
o systematic random sampling
o voluntary sampling
o cluster sampling
o convenience sampling

Explanation:

Voluntary sampling occurs when individuals themselves decide whether to participate in a survey. Here, customers are asked to voluntarily stay on the line to answer the survey questions. It's not systematic random sampling (no fixed - interval selection), not cluster sampling (no division into clusters), and not convenience sampling (not just using the most readily available group in a non - voluntary sense).

Answer:

voluntary sampling
