This document provides examples of Weibull distribution analysis. The first example analyzes failure data with a shape parameter of 3.5, operating time of 2000 hours, test time of 7000 hours, and 3 tests with a reliability of 0.99. The analysis estimated a scale parameter of 7444.5 hours and a confidence level of 0.91. The second example analyzed 99 operating units with no failures and estimated a scale parameter of 10078.8 hours and a confidence level of 0.87.
