genderweight: Weight Data By Gender for Two-Samples Mean Test

Description

Contains the weights by sex (M for male; F for female). The question is whether the average women's weight differs from the average men's weight?

A two-samples independent t-test can be performed to answer to this question.

It is the data set used in the Datanovia tutorial “T-Test in R: One-Sample, Independent (Student & Welch) & Paired” (https://www.datanovia.com/learn/biostatistics/two-groups/t-test-in-r).
