O Since In) has a normal distribution, by definition e has a normal distribution. O Since In has a normal distribution, by definition has a lognormal distribution. O since In has a lognormal distribution, by definition has an exponential distribution. O Since In has a normal distribution, by definition has an exponential distribution.
