Hypothesis TestingHypothesis testing is more intuitive when the confidence interval method is used (as shown here from pages 253-254 of Chapter 10). The traditional t-statistic is also presented in detail.

Bivariate Data ExamplesRelationships and regression are powerful business concepts. Here are a couple of the examples from Chapter 11 on Bivariate Data (pages 295 and 308).
