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

interval_estimate3(x, sigma = -1, alpha = 0.05)

Arguments

x	A numeric vector.
sigma	The standard deviation of the population. sigma>=0 indicates it is known, sigma<0 indicates it is unknown. Default to unknown standard deviation.
alpha	The significance level, a real number in [0, 1]. Default to 0.05. 1-alpha is the degree of confidence.

Value

A data.frame with variables:

mean	The sample mean.
a	The confidence lower limit.
b	The confidence upper limit.
