Definitions:

Margin of Error

The range within which the true population parameter is expected to lie, with a certain level of confidence.

Confidence

In statistics, it often pertains to the degree of certainty or probability that a parameter falls within a specified range.

Population Variance

A measure of the spread of a distribution within an entire population, indicating how much the data differ from the mean.

T Distribution

A probability distribution that emerges in the context of estimating the mean for a normally distributed population, applicable when dealing with a small sample size and the population standard deviation is not known.
