Hello, group. Happy new year!

I was trying to estimate the correct sample size when the
population is a sysmetric distribution with discrete variable (sort of
like Poisson distribution, the expected value is 0). supposed that I
have a group sample with n observation. How to calculate the minimum
sample size to let me guarantee that the mean of the distribution is 0.

Thanks very much for your help.
