Calculate Confidence Interval

Description

Calculate the confidence interval of a given sample mean.

Usage

conf_int(x, ci = 0.95, r = NA, s = NA, se = NA, n = NA)

Arguments

x	A sample mean
ci	Numeric, confidence level (default = 0.95)
r	Numeric, correlation coefficient (default = NA)
s	Numeric, standard deviation of population (default = NA)
se	Numeric, standard error of the sample mean (default = s * sqrt(1 - r))
n	Numeric, sample size (default = NA)

Value

A list containing confidence intervals from Z and t methods.

Examples

conf_int(x = 12, ci = 0.99, s = 2.5, n = 24)
conf_int(x = 12, s = 2.5, r = 0.6)
