Khan Academy: Interpreting a Z Interval for a Proportion
Once we build a confidence interval for a proportion, it's important to be able to interpret what the interval tells us about the population, and what it doesn't tell us. Let's look at few examples that demonstrate how to interpret a...

Texas Gateway: A Single Population Mean Using the Normal Distribution
This lesson explains how to calculate and interpret the confidence interval for a population mean. It also looks at the effect on the confidence interval of changing the confidence level or sample size. It then explains how to find the...

Khan Academy: Reference: Conditions for Inference on a Proportion
When we want to carry out inferences on one proportion (build a confidence interval or do a significance test), the accuracy of our methods depend on a few conditions. Before doing the actual computations of the interval or test, it's...

Texas Instruments: Determining Sample Size for a Given Margin of Error
This set contains questions about statistics involving how to choose a sample size to fit a desired maximum error bound. The student learns to do this on confidence intervals for proportions as well as confidence intervals for means.

Texas Instruments: Tests of Significance
Students understand how tests of significance can be performed with confidence intervals. They use a simulation to clarify the meaning of a hypothesis. Students examine large sample tests for a proportion, mean, difference between two...

Khan Academy: Making a T Interval for Paired Data
In some studies, we make two observations on the same individual. For instance, we might look at each student's pre-test and post-test scores in a course. In other studies, we might make an observation on each of two similar individuals.
