APFIVE A polling expert contends that the existence of sampling error renders public opinion polls too unreliable for serious analysis. Which of the following statements most directly undermines this contention?
Historical analyses reveal that sampling error has remained a persistent issue even with increased sample sizes in modern polls.
Studies have shown that increasing the number of respondents in polls has significantly reduced sampling error, as verified by the more precise predictions of exit polls in recent elections.
The reliance on traditional random sampling methods in older polls often produced less accurate predictions than more recent non-random techniques.
Systematic reviews suggest that sampling error is large enough to consistently distort poll results, thus validating concerns over poll reliability.
