Question

Sample A has a count of 30 successes withn 100 and Sample B has a count of 50 successes with 250. Use StatKey or other technology to generate a bootstrap distribution of sample differences in proportions and find the standard error for that distribution. Compare the result to the value obtained using the formula for the standard error of a difference in proportions from this section.

Answer 1

Standard error is 0. 052

Explanation:

Bootstrapping is a method that estimates the sampling distribution by taking multiple samples with replacement from a single random sample. These repeated samples are called resamples. Each resample is the same size as the original sample.
