What is the expected life of the component

Reference no: EM131384464

The time to failure of a mechanical component under friction may be modeled by a Weibull distribution with γˆ= 20 days, βˆ= 0.2, and α = 35 days.

(a) What proportion of these components will fail within 30 days?

(b) What is the expected life of the component?
