Statistical Hypothesis Testing
system failure at least 3,000? Statistical hypothesis testing is a vehicle for answering these questions. Care must be taken in setting up the hypothesis test to ensure that the analysis performed addresses the test objective. Too often DoD testing includes “implied” hypothesis tests in which the actual hypotheses are never explicitly stated!

A Practical Guide for Interpreting Confidence Intervals
www.afit.eduConfidence intervals allow us to take information from a sample and use it to form an interval estimate for a population parameter or function of parameters. In DoD testing , confidence intervals are often calculated for almost every performance measure (such as mean time between failures, proportions, etc.) required for the evaluation. Up
