The lifetime of a semiconductor laser has a lognormal distribution, and it is known that the mean and standard deviation of lifetime are 10000 and 20000, respectively. (a) Calculate the parameters of the lognormal distribution. (Round the answers to 4 decimal places.) 0 = i @= i (b) Determine the probability that a lifetime exceeds 10100 hours. (Round the answer to 3 decimal places.) i (c) Determine the lifetime that is exceeded by 90% of lasers. (Round the answer to 1 decimal place.) i hours
