Definitions:

Confidence Interval

An array of values, extracted from sample statistics, considered likely to have within it the value of an unknown population parameter.

Population Variance

Population variance is a measure of the dispersion among numbers in a population set, indicating how much individual numbers differ from the population mean.

Normally Distributed

A distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Confidence Interval

Values range, derived from statistical samples, that possibly includes the value of an elusive population parameter.
