The Interval Estimation Worksheet demonstrates how changes in the variance, sample size, and confidence level effect the confidence intervals for a population mean. You may change the values of the variance, sample size, and the confidence level. The population mean value is fixed at 2,000. You may not change the cells in red. While it is not a strict requirement, the confidence interval graph is best displayed if variance values are between 400 and 10,000. The percent of intervals containing the true mean indicates the percentage of
