Two sided interval estimation of mu
of one non-normal sample with large sample size
Description
Compute the two sided interval estimation of mu
of one non-normal sample with large sample size when the population variance is known or unknown.
Usage

Arguments
x |
A numeric vector. |
sigma |
The standard deviation of the population. |
alpha |
The significance level, a real number in [0, 1]. Default to 0.05. 1-alpha is the degree of confidence. |
