A) mean of the original sample
B) mean of the distribution of sample means
C) zero
D) mean of the test

Question

Quizplus · Accepted Answer

Bootstrapping is a resampling technique that involves repeatedly drawing samples from a data set and calculating statistics based on these samples. In this case, we would repeatedly draw samples of size 8 with replacement from the original data set and calculate the mean for each sample. The resulting distribution of sample means would be used to construct a confidence interval. The center of this confidence interval would be the mean of the original sample, which is the best estimate for the population mean. Therefore, the correct choice is A - mean of the original sample.
