The observed annual maximum runoff, X, in the Kızılırmak River has been modelled by a normal distribution with parameters, µx = 256.7 m³/sec and ox = 191 m³/sec. a) Compute the probability that X > 400 m³/sec according to the normal distribution model. b) If X is now assumed to be lognormally distributed, find the parameters of this lognormal distribution and again compute the probability that X > 400 m³/sec according to the lognormal model. c) Compare the probabilities you have computed according to this two models. Why are the results different? Comment.
