Confidence Intervals for Means

Published on 12/21/2011

Activity Overview

This activity investigates generating a confidence interval for the mean of a random sample of size 100 from an unknown population.

Objectives

  • Students will interpret a confidence interval for a population mean as an estimated range of values that is likely to contain the actual population mean.
  • Students will recognize that a confidence interval is calculated from a set of sample data for samples selected from known populations.
  • Students will recognize that a confidence interval for a population parameter from an unknown population is based on knowing how statistics from samples drawn from known populations behave.
