Quick Prep Links Review material on calculating and interpreting sample means and standard deviations. Review the normal distribution. Make sure you understand the concepts associated with sampling distributions for x and p. Review the steps for developing confidence interval estimates for a single population mean and a single population proportion. Review the methods for testing hypotheses about single population means and single population proportions. Estimation and Hypothesis Testing for Two Population Parameters 1 Estimation for Two Population Means Using Independent Samples Outcome 1. Discuss the logic behind and demonstrate the techniques for using independent samples to test hypotheses and develop interval estimates for the difference between two population means. 2 Hypothesis Tests for Two Population Means Using Independent Samples 3 Interval Estimation and Hypothesis Tests for Paired Samples Outcome 2. Develop confidence interval estimates and conduct hypothesis tests for the difference between two population means for paired samples. 4 Estimation and Hypothesis Tests for Two Population Proportions Outcome 3. Carry out hypothesis tests and establish interval estimates, using sample data, for the difference between two population proportions. Why you need to know In many business decision-making situations, managers must decide between two or more alternatives. For example, fleet managers in large companies must decide which model and make of car to purchase next year. Airlines must decide whether to purchase replacement planes from Boeing or Airbus. When deciding on a new advertising campaign, a company may need to evaluate .
