Actuarial Statistics Problem - Lognormal Distribution


New member
Nov 16, 2015
An analysis of 3000 household theft claims reveal a mean claim size of 1500 and a standard deviation of 600. Assuming claim be modeled by a lognormal distribution, eestimate the proportions of claims < 1000, and the claim size M with the property that 1000 of the claims would be expected to exceed M.

I'm having particular difficult with this problem. Any suggestions?
