null and alternative hypotheses in mathematical terms as well as in words.
Step by step
Solved in 2 steps
- Mutually exclusive hypotheses state that the hypotheses formulated should be different from one another.Conclusion: Fail to reject Null hypothesis or reject Null hypothesisAlternative hypothesis is everything except Represents a theory that has been put forward Frequently “alternative” is actual desired conclusion of the researcher Only considered if H0 is rejected. Opposite of Null Hypothesis.
- Create two problems in testing hypothesis. Determine the given and formulate the null and alternative hypotheses. Write your answer in your notebook.“Hypothesis testing is an important aspect without which the validity of research can’t be claimed”. Comment on the statement with valid examples to prove this.
