A component has a Weibull failure time with parameters a = 4.5 and λ = 0.1.
(a) What is the probability that the component is still operating at time 12?
(b) What is the probability that the component fails before time 8?
(c) What is the median failure time?
(d) What is the hazard rate?
(e) How much more likely to suddenly fail is a component operating at time 12 compared with a component operating at time 8?
