The Gaussian distribution arises in many contexts and is widely used for modeling continuous random variables. Cancellation because variabilities accumulate and intermediate levels get started let a make sure you know how combine. First we find $Z=g^{-1}(y)={y\over{\sigma}}$ and ${d\over{dy}}{g^{-1}(y)}={1\over{\sigma}}$. Multiplication by c always multiplies the variance of a random variable by c and the mean by c. The normal distributions are rather special in that multiplication by a constant preserves the fact of being normal; this can be seen from considering the density.
