Confidence Intervals for Proportions

Activity Overview

This lesson involves the concept of confidence intervals as a tool to make statements about a population proportion based on a given sample.

Objectives

  • Students will interpret a confidence interval for a population proportion as a set of populations that seem reasonable as candidates for populations that could produce a sample with the observed proportion.
  • Students will recognize that a confidence interval is calculated from a given set of sample data.
  • Students will recognize that a confidence interval from a sample statistic from an unknown population is based on knowing how statistics from samples drawn from known populations behave.
