  • confidence interval;
  • finite-population central limit theorem;
  • sampling distribution


A confidence interval procedure uses the data to determine an interval with the property that—viewed before the sample is selected—the interval has a given high probability of containing the true population value. This chapter begins wit a discussion of confidence interval for the population mean or total. It then explains finite-population central limit theorem and sampling distributions. One way to look at the sampling distribution of an estimator those results from using a particular design with a particular population is to use a very small population and small sample size, so that every possible sample may be listed. Finally, the chapter presents notes on confidence interval computation.
