Step-by-step explanation:
Hypothesis:
- It is an assumption or explanation that need to be tested.
- It determines the claim in the testing.
- There are two types of hypothesis: Null hypothesis and alternate hypothesis.

- Alternate hypothesis states that the sample does not belong to the defined population.
A hypothesis is a testable claim or statement, that is yet to be tested, concerning the relationship among variables that can be observed.
