A simple random sample of 30 widgets is drawn from a manufacturing lot of 200 widgets. The widgets in the sample are run until they fail. 8 of the widgets in the sample last more than 3,000 hours.
An unbiased estimate of the fraction of widgets in the manufacturing lot that will last more than 3,000 hours is .
The finite population correction for the standard error of the sample percentage is
The largest the standard error of the sample percentage could be is
The bootstrap estimate of the standard error of the sample percentage is
The bootstrap estimate of the standard error of the sample percentage is (unbiased OR biased)
