What is the meaning of Null Hypothesis?
- Difference between two parameter mean is zero
- The difference is due to error in sampling
- Both A & B
- None of these
Explanation
The null hypothesis (often denoted as (H 0) is a fundamental concept in statistical hypothesis testing.
It typically states that there is no effect or no difference, and any observed effect or difference is due to random chance or sampling error.
Both A & B: This is correct because the null hypothesis often includes the notion that there is no significant difference between parameters (A) and that any observed difference is due to random sampling error (B).
