Jan 11, 2021 at 13:02 comment added Three Diag Sum of exponential is gamma distributed, so you can compute the probability of the realization of the sample mean exactly (i. E. The pvalue)

Jan 10, 2021 at 17:33 comment added Three Diag But why are you using a t-test? Sample mean is only approximately normal, but you might be able to do better than that given you variables are exponential and their sum follows a gamma distribution.
