View Resource Rice Virtual Lab in Statistics Confidence Intervals

This applet simulates sampling from a population with a mean of 50 and a standard deviation of 10. For each sample, the 95% and 99% confidence intervals on the mean are computed based on the sample mean and sample standard deviation. Exercises accompany the applet to help students understand what confidence intervals mean.
