Definitions:

Standard Error

A statistical measure of the variance or standard deviation of a sample mean, indicating the precision with which a sample represents a population.

Assembly Lines

Manufacturing processes in which parts are added to a product in a sequential manner using optimally planned workflows to create a finished product much faster than with traditional methods.

Test Statistic

A value calculated from sample data during a hypothesis test used to determine whether to reject the null hypothesis.

Critical Value

A threshold value that defines the boundary of the rejection region in hypothesis testing, beyond which the null hypothesis is rejected.
