Question

BlackTom AI · Accepted Answer

The question describes a survey conducted on a random sample of 1,000 Korean voters to measure support for a welfare policy, with 600 of the 1,000 supporting the current policy.
Option: '표본은 임의로 추출하여 조사한 1,000명 중 현행 정책을 지지한 600명이다.'
- This statement is a straightforward factual description of the sample: the sample is 1,000 individuals selected randomly (임의로 추출하여) and among them 600 support the current policy. It correctly identifies both the sample size and the number of supporters within that sample, which is a typical way to summarize survey data.
- There is no assertion here about population parameters, inference procedures, or generalizations beyond the sample data. It simply restates the sampled individuals and the observed count of supporters, which is a valid description of the sample itself.
- From a sampling theory perspective, describing the sample as random (임의로 추출) is important because it supports the assumption that the sample is representative of the population in expectation, enabling estimation of population proportions and conducting hypothesis tests or confidence interval construction.
- However, since the question asks which statement is false (다음 중 틀린 설명은), we should check what the other options would say. In this given set, only one option is provided. Without additional options, we cannot identify a false statement among them. The provided option logically describes the sample accurately and is not itself false.
- If we were to consider potential common tricky points: this statement does not claim that 600/1000 exactly represents the population proportion; it merely reports the sample result, which is correct. It also does not conflate sample proportion with population proportion or make unwarranted generalizations.
- In summary, the single option given correctly describes the sample, and since no other statements are provided to be evaluated as true or false, there is no false statement among the listed content.
