Hypothesis Test for a Proportion

Hypothesis Test for a Proportion

This Java applet tutorial prompts the user to input the components of a hypothesis test for a proportion. Hints are provided whenever the user enters an incorrect value. Once the steps are completed and the user has chosen the correct conclusion for accepting or rejecting the null hypothesis, a statement summarizing the conclusion is displayed. The applet is supported by an explanation of the steps in hypothesis testing and a description of one-tailed and two-tailed tests.

This offers a nice option for students to practice identifying components of a hypothesis test. I would use the p-value approach rather than the rejection region approach. A link is provided to have you switch to the p-value method.


I don't like using "r" to count the number of successes. This is very confusing and some students might mistake this for the coorelation coefficent.

A tutorial that is not especially useful. It uses critical value rather than p-value, so I would not use it in my classes. It uses r for the number of successes rather than x. It does not explain very well what it is asking for. Students must be given a tutorial before using. For example, when it asked for "p", I thought it wanted me to solve for the z-value and get the p-value. Actually it was asking for the proportion for the sample. It uses "reject the null" rather than talking about "evidence of a significant ...". It does not indicate whether or not my answer is correct. I might have used this twenty years ago but in my class, this tutorial is out-of-date.

Students often have trouble identifying values that go into a formula from a word problem. This applet provides practice. I would like to see a table with critical values included
