Introduction: Distribution of Sample Proportions

What you’ll learn to do: Describe the sampling distribution for sample proportions and use it to identify unusual (and more common) sample results.

LEARNING OBJECTIVES

  • Describe the sampling distribution for sample proportions and use it to identify unusual (and more common) sample results.
  • Distinguish between a sample statistic and a population parameter.
  • Use a z-score and the standard normal model to estimate probabilities of specified events.
