Interval Estimation
It is a common requirement to efficiently estimate population parameters based
on simple random sample data. In the R tutorials of this section, we demonstrate
how to compute the estimates. The steps are to be illustrated with a built-in data
frame named survey. It is the outcome of a Statistics student survey in an
Australian university.
The data set belongs to the MASS package, which has to be pre-loaded into the R workspace prior to use.
