A bootstrap estimate is obtained by repeatedly drawing samples from the original sample. These repeated draws are usually made:
Correct answer: A. With replacement from the observed sample
- A. With replacement from the observed sample
- B. Without replacement from the population
- C. From every population unit exactly once
- D. Only from units with missing responses
Explanation
Bootstrap resampling repeatedly draws, with replacement, from the observed sample to approximate the sampling distribution of a statistic. It does not require direct access to the full population.

About Sampling and Estimation
Sampling covers population and sample, sampling frames, simple random, systematic, stratified, cluster and convenience methods, along with sampling and non-sampling errors. Estimation includes sample statistics, population parameters, point estimates, confidence intervals and margins of error, with attention to how sample size affects precision.
