  if p is a generic value (i.e. not a probability) and you know the
variance (and are willing to assume normality) then you can indeed
use the delta method; there are a variety of other techniques
if you have the original data: fitting profile confidence limits, various
resampling methods including bootstrapping, etc.
(See section 6 of chapter 7 at http://www.zoo.ufl.edu/emdbook for
more details if you like).
