Hi,

The product's lifetime distribution is modeled by the Weibull distribution with scale = 44, shape = 4

In JMP Demonstration Explorer for Parametric Reliability, I input the following:

Alpha: 0.2

Distribution: Weibull

Demonstration time: 100

Demonstration Reliability: 0.98

Weibull beta: 4

Maximum failures allowed: 0

Sample size: 10

Solve for Test time = 168

Why scale parameter is not used?

Thanks.
