Expert Solution

Instruction

A hypothesis is a preliminary explanation for a group of facts that can be put to the test by specific follow-up research.

Basically, there are two types of hypothesis : null hypotheses and alternative hypotheses.

A statistical hypothesis known as a "null hypothesis" asserts that there is no statistical significance can be found in a particular set of observations.

A statistical claim that there is a significant difference between the set of variables and is made in the context of hypothesis testing is known as alternate hypothesis.
