Definitions:

Null Hypothesis

A statistical hypothesis that suggests there is no significant effect or difference between certain data sets or variables.

One-Tail T-Test

A statistical hypothesis test used to determine if there is a significant difference in the means of two groups in one direction.

Level Of Significance

The level of significance, often denoted by alpha, is a threshold set for deciding whether to reject the null hypothesis, typically set at values like 0.05 or 0.01.

Rejection Region

The rejection region is the range of values in hypothesis testing that leads to the rejection of the null hypothesis if the test statistic falls within this range.
