CIMean

<p>A data frame from which var is drawn.</p>

data

<p>An app to investigate how sample size and confidence level affect the width of a confidence interval.  
A sample is drawn from the input population and a confidence interval for
the population mean is calculated.  The kernel density plot for the population
and the histogram for each new sample are plotted, along with the confidence
interval.  Summary information is output to the console to tally the number of times
the computed confidence interval covers the true population mean and how many times
it misses.  There is an option to draw 100 or 1000 samples at a time.</p>

A collection of data sets and functions that are useful in the
teaching of statistics at an elementary level to students who may have
little or no previous experience with the command line.  The functions for
elementary inferential procedures follow a uniform interface for user
input.  Some of the functions are instructional applets that can only be
run on the R Studio integrated development environment with package
'manipulate' installed.  Other instructional applets are Shiny apps
that may be run locally. In teaching the package is used alongside of
package 'mosaic', 'mosaicData' and 'abd', which are therefore listed as
dependencies.
