Definitions:

T-statistic

A ratio used in hypothesis testing that compares the difference between an observed sample mean and a hypothetical population mean to the standard error of the mean.

Alpha

A coefficient that often represents the level of significance in hypothesis testing, marking the threshold for rejecting the null hypothesis.

Critical Value
