Accepted Solution
A:
Answer:C) The survey is meaningless because of voluntary response bias.Step-by-step explanation:Voluntary response bias happens when the people that are surveyed volunteer themselves to answer the questions. Only people with a strong opinion, either in favor or against, tend to offer themselves as voluntary subjects. This same problem happens when radio or TV hosts decide to solicit their audience participation, only people with strong feelings will participate since it is optional. People that are relatively indifferent to the subject will not participate in the survey. This is why most voluntary surveys tend to lean towards extreme answers.
