Hypothesis Testing for Proportions

A sample can tell us a lot about a population—but how do we know if the evidence is strong enough to support a claim?

In this video, we introduce hypothesis testing for population proportions and learn how to use sample data to evaluate claims about a population.

We'll work through the entire hypothesis testing process step by step, including how to set up hypotheses, calculate a test statistic, interpret a p-value, and make a conclusion in context.

Topics covered:
• Null and alternative hypotheses
• Significance level
• Test statistics and p-values
• One-proportion z-tests
• Type I and Type II errors
• Interpreting results in context

By the end of this video, you'll understand not only how to perform a hypothesis test, but what the results actually mean.
