Here are some papers that may be useful, however after unsuccesfully
trying to decipher them and apply them, I used a bootstrap

Confidence Intervals for the Coefficient of Variation for the Normal and Log
Normal Distributions
L. H. Koopmans; D. B. Owen; J. I. Rosenblatt
Biometrika, Vol. 51, No. 1/2. (Jun., 1964), pp. 25-32.

Confidence Intervals for a Normal Coefficient of Variation
Mark G. Vangel
The American Statistician, Vol. 50, No. 1. (Feb., 1996), pp. 21-26.
