Interval Estimate of Population Mean with Known Variance

A tutorial on computing the interval estimate of population mean at given confidence level. The variance of the population is assumed to be known.

Point Estimate of Population Mean

A tutorial on computing the point estimate of population mean from a simple random sample.

Interval Estimation

fractal-01h 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.
