Answer: Bootstrap method
The **bootstrap method** is correct because it involves repeatedly drawing samples from the original sample, with each resample being of the same size as the original. Importantly, each item drawn is replaced back into the group, allowing it to be drawn multiple times. This method is particularly useful for estimating the standard error of the sample mean by computing the mean of each resample. - **Cluster sampling** (Option B) is incorrect because it involves selecting elements from the population, not an original sample. The population is divided into clusters, which are then randomly selected. - **Convenience sampling** (Option C) is also incorrect, as it involves selecting elements from the population based on accessibility, which may not be representative of the entire population.
