    Law

    I'm looking for the confidence interval (of the mean). I have the mean, the standard deviation, and the population is very large.

    But, I have no idea what law the distribution is following.

    Can I still find the confidence interval of the mean ?

    So... even if I don't know the law, according to the central limit theorem, the distribution will approach a normal distribution.

    Since n is large (I assume n > 50 or so?), yes.
