This Weibull++ Quick Start Guide models using the Expected Failure Time Plot to determine what range of failure times you can expect to observe on each unit of bulb B during this test, assuming bulb A and bulb B have the same reliability, and comparing the failure times to the expected times, as the units of bulb B fail during the test.
