Q1: Lifetimes of a certain component are lognormally distributed with parameters u = 1 day and o = 0.5 days. Find the mean lifetime of these components. 1-Find the standard deviation of the lifetimes. 2-Find CDF 3- Find reliability at t= 4 day Q2: The lifetime (in days) of a certain electronic component that operates in a high-temperature environment is lognormally distributed with u = 1.2 and o = 2. a. Find the mean lifetime. b. Find the probability that a component lasts between three and six days. c. Find the 95th percentile of the lifetimes. d- find CDF Q3: 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 T 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
