Definitions:

Confidence Interval

A set of values, calculated from sample statistics, predicted to hold the value of an unobserved population parameter.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the values differ from the mean.

T-Distribution

A probability distribution used in statistics that arises when estimating the mean of a normally distributed population in situations where the sample size is small and population variance is unknown.

Confidence Interval

A range of values, derived from the sample data, that is believed, with a certain degree of probability, to contain the true population parameter.
