Step by step solution

Concept introduction

A hypothesis is a reasonable assumption for a behaviour (plural hypotheses). The scholarly approach involves that an assumption be validated before it can be deemed a factual prediction. Technical speculations are mainly influenced by past results that cannot be fully addressed by established scientific findings.

Explanation

It can be used to see if two populations have the same distribution or not. The t - statistics for a testing of homogeneity and a testing of independence are computed using the same method. The independence test looks at whether two or more variables are mutually excluded. Verify whether two data sets are drawn from the same distribution. You must have an expected value of at least five for each cell to use the homogeneity test.
