03: The authors suggest using a Weibull distribution to model the duration of a bake step in the manufacture of a semiconductor. Let T represent the duration in hours of the bake step for a randomly chosen lot. If I Weibull(0.3, 0.1), what is the probability that the bake step takes longer than four hours? What is the probability that it takes between two and seven hours? What reliability at t=0.8 hours 03: The authors suggest using a Weibull distribution to model the duration of a bake step in the manufacture of a semiconductor.
