What does the Weibull shape parameter β indicate about failure behavior?

• A. β < 1 indicates early-life failures, β = 1 indicates random failures, β > 1 indicates wear-out failures.
• B. β < 1 indicates wear-out, β = 1 random, β > 1 early-life.
• C. β < 1 indicates random, β = 1 wear-out, β > 1 early-life.
• D. β < 1 indicates constant hazard, β = 1 decreasing hazard, β > 1 increasing hazard.

Answer: (A)
