Chapter 8: Inference for Proportions

In this chapter, you'll learn:

  • To construct and interpret a confidence interval to estimate the proportion of successes in a binomial population
  • To use a significance test (hypothesis test) to decide if it is reasonable to conclude that their sample might have been drawn from a binomial population with a specified proportion of successes
  • To construct and interpret a confidence interval for the difference between the proportion of successes in one population and the proportion of successes in another population
  • To use a test of significance to decide if it is reasonable to conclude that two samples might have been drawn from two binomial populations that have the same proportion of successes
  • To construct and interpret confidence intervals and tests of significance for experiments
