Which of the following is the most likely advantage of using bootstrap resampling to construct a confidence interval for a statistic?
The bootstrap can be applied without assuming a specific population distribution, because it builds the sampling distribution from the observed data itself. It still requires a representative original sample and does not guarantee smaller standard errors than analytical formulas.
- AIt guarantees a smaller standard error than the analytical formula
- BIt removes the need for the original sample to be representative
- CIt can be applied without assuming a specific distribution for the populationCorrect
Explanation
The bootstrap uses the empirical distribution of the observed data, so it does not require a distributional assumption or a formula for the statistic. It still relies on a representative sample and does not guarantee a smaller standard error.
Did you get it right without looking?
One question tells you little. A timed set on Estimation and Hypothesis Testing shows your real accuracy, how long you take and where you lose marks.
