The problem is to find the (parametric?) distribution of the ratio
low/high in connection with Brownian motions. The application I have in
mind is daily low/high or 52-week low/high for any particular stock
price. I would like to add a result on this subject in my section
"theorems" on my web sit

I think that your colleague made at least one error here. The unpooled t is
not necessarily more conservative. If it had been the group with the
smaller variance (.02) that had the larger sample sizes, the resulting t
would have been considerably larger. The important thing is whether the
