Definitions:

Alpha

Alpha, often represented as α, is the threshold probability of committing a Type I Error, typically set at 0.05 or 5% in hypothesis testing.

T-statistic

The T-statistic is a ratio used in hypothesis testing that compares the difference between an observed sample mean and a known value, to the standard error of the mean.

Null Hypothesis

A default hypothesis that there is no significant difference or effect, typically set against the alternative hypothesis in statistical testing.

Alpha

A coefficient used in statistics that represents the level of significance, often denoted as the probability of rejecting a true null hypothesis.
