Brief Review of Hypothesis Testing Concepts/Issues and Confidence Intervals

Statistical techniques are used for purposes such as estimating population parameters using either point estimates or interval estimates, developing models, and testing hypotheses. The first section of this chapter discusses the basic concepts of hypothesis testing. The second section presents reviews of confidence intervals and their relationship to hypothesis tests. Sample size for confidence intervals can be determined using MINITAB. Professional sports teams do a form of testing all of the time when they make decisions regarding individual players. This is briefly discussed in the third section. The fourth section talks about observed, retrospective, conditional, and predictive power. The fifth section provides insight on testing for equality, equivalence, noninferiority, or superiority. Bioequivalence testing is an important part of hypothesis testing.
