Plotting random samples of confidence intervals around the mean

This function takes some parameters and simulates random samples and their confidence intervals

OurConf(samples = 100, n = 30, mu = 0, sigma = 1, conf.level = 0.95)

Arguments

samples	The number of times to draw random samples
n	The sample size we draw each time
mu	The population mean mu
sigma	The population standard deviation
conf.level	What confidence level to compute 1 - alpha (significance level)

Value

A ggplot2 object

Examples

OurConf(samples = 100, n = 30, mu = 0, sigma = 1, conf.level = 0.95)
#> 90 % of the confidence intervals contain Mu = 0 . 
OurConf(samples = 2, n = 5)
#> 100 % of the confidence intervals contain Mu = 0 . 
OurConf(samples = 25, n = 25, mu = 100, sigma = 20, conf.level = 0.99)
#> 100 % of the confidence intervals contain Mu = 100 .
