Logo for Confidence Interval for a Proportion
This Java applet tutorial provides a series of word problems on determining confidence intervals. Each problem prompts the user to input the steps for determining a confidence interval for a proportion. Hints are provided whenever the user enters an incorrect value. Once the steps are completed, a statement summarizing the interval obtained is displayed. The applet is supported by an explanation of the steps in creating confidence intervals

This is helpful for practicing 1-sample proportion calculations. It would be nice to see references to the "population proportion" to explain why confidence intervals are performed. This would be useful for a student to use independently once or twice, but it would be hard to use in a classroom setting.

Technical Remarks:

I like how the tutorial politely corrects you when you make a mistake at each step so the mistakes don't snowball. I think it would be a good idea to add in a calculator to this applet to make it self-contained.

This would be good for students to practice calculating confidence intervals. Not very useful in a classroom setting.
