What is Weibull model made out of?
- A.
Dose-Response Model
- B.
Fluid Flow Model
- C.
Population Growth Model
- D.
Cancer Rate Model
Correct Answer
A. Dose-Response ModelExplanation
The Weibull model is a statistical model commonly used in reliability engineering to analyze the failure rates of systems. It is particularly useful for modeling the time-to-failure of a component or system. The model is based on the dose-response concept, which relates the effect of a stimulus (dose) on a biological system (response). In this case, the dose refers to the stress or load applied to the system, and the response is the failure time. Therefore, the Weibull model is made out of the dose-response model.Rate this question:
