WebbThe lifetime of light bulbs follows an exponential distribution with a hazard rate of 0.001 failures per hour of use (a) Find the mean lifetime of a randomly selected light bulb. Answer: Let X denote the lifetime of light bulbs,then the hazard rate h(x) = 0.001. So the survival function S(x) = exp{-∫ 1 1000 𝑥 0} = exp{−𝑥 1000
