Question

Quizplus · Accepted Answer

The bathtub-shaped hazard function of reliability describes how the failure rate of a product is high at the beginning (early-life failures), decreases and remains low during its useful life (random failures), and then increases again as the product ages (wear-out failures). This shape resembles a bathtub curve.
