Simulating Confidence Intervals
This applet allows users to generate confidence intervals for either means or proportions. Users set the parameters including the number of samples and click "Sample." The applet graphs the intervals such that intervals containing the true mean or proportion are in green, while intervals not containing the true mean or proportion are in red. The true mean or proportion is shown by a blue line.

This is used by students in an Intro class, without instructor interaction. Easy for them to use, and illustrates several key ideas.

Going through the steps of the problems posed in this applet should serve to help students be able to identify all the necessary information to perform a hypothesis test. This applet does not use the p-value approach but rather compares the z-score to a z-critical value.

This applet has features (including a running total of confidence intervals covering the true parameter value and the sort option) which could potentially help a student better understand the concepts of confidence interval and level. One detail worth mentioning: you can see that the width of the confidence intervals differ when using the 't' option. An instructor could use this as an opportunity to illustrate that different samples will have different sample standard deviations.
