mean and Standard deviation of ratio of normal variables?

17 views (last 30 days)
If we have, Z=X / Y,
where X and Y have different means and normally distributed, then
what is the mean and standard deviation of Z?
We know that is a Cauchy Distribution, so Z may be approximately normally distributed. Here is the Journal article discussing the ratio of normal variables:
My question is, can we find exact distribution of Z ?
