**Problem 22**

Let \( Z \sim N(0,1) \). If we define \( X = e^{\sigma Z + \mu} \), then we say that \( X \) has a log-normal distribution with parameters \(\mu\) and \(\sigma\), and we write \( X \sim LogNormal(\mu, \sigma) \).

a. If \( X \sim LogNormal(\mu, \sigma) \), find the CDF of \( X \) in terms of the \(\Phi\) function.

b. Find \( E(X) \) and \( Var(X) \).
