Definitions:

Normal Populations

Populations that exhibit a bell-shaped distribution curve, characterized by symmetry around the mean and decreasing frequency as the distance from the mean increases.

Independent Samples

Refers to two or more groups of samples that are collected from distinct, non-overlapping populations, without any pairs or matched subjects.

Sampling Distribution

Distribution of probabilities associated with a particular statistic, originating from a random sample.

Independent Samples

Samples that are collected from separate populations and are not related or paired in any way, ensuring that the observations are independent of each other.
