Example: Test design to demonstrate reliability given a stress distribution

Assume that the following date set is random sample of usage loads for a particular component in some unit U.
 * 480; 645; 720; 950; 975; 1,175

Furthermore assume that we wish to achieve, as well as demonstrate, a reliability of 99.9% at a 90% confidence in our design.

Step 1: Compute the Stress Distribution
Using Weibull++ a Weibull distribution was fitted to the data:
 * Distribution: 	Weibull-2P
 * Analysis: 	RRX
 * Ranking: 	MED
 * Beta:	3.2839
 * Eta (U):	919.9457
 * Rho:	0.9901
