# 8.2: Introduction to Estimating a Population Proportion


## What you’ll learn to do: Construct a confidence interval to estimate a population proportion.

In this section, we will continue studying the estimation of a proportion with a confidence interval. We will recognize situations that call for testing a claim about a population or estimating a population proportion. We will learn to construct a confidence interval to estimate a population proportion when certain conditions are met and interpret this interval in context. We also will learn how to interpret the meaning of a confidence level and relate it to the margin of error. These tools can be used in many applications from sports attendances to online medical tools.
