Question: Let Z N(0, 1). If we define X = e Z+ , then we say that X has a log-normal distribution with parameters

Let Z ∼ N(0, 1). If we define X = eσZ+μ, then we say that X has a log-normal distribution with parameters μ and σ, and we write X ∼ LogNormal(μ, σ).

a. If X ∼ LogNormal(μ,σ), find the CDF of X in terms of the Φ function.

b. Find EX and Var(X).
