Before explaining about Null Hypothesis, let us discuss about the conception of Hypothesis.
Hypothesis is a statement about a population parameter or population distribution. Any statement that should be tested for discovering the authenticity in order to making a decision is Hypothesis.
Any claim by a producer against his product is simply a hypothesis that should be tested by the customer that the claim is true or not in order to make a decision to purchase or not.
Two set of hypothesis may found in a hypothesis testing. Null hypothesis and alternative hypothesis.
The true statement from a pair of hypothesis is termed as Null hypothesis and other statement is alternative hypothesis.
Hypothesis testing is used for making a decision to accept or reject any of the statement. Accepting or rejecting of statement is depends of the true evidence against the statement.
Let consider about any statement of any product stability claimed by producer equal or less from the product stability of existing supplier, then it should not very good thinking to switch to new supplier from the existing supplier. But, if the stability is very higher from the existing supplier then it should be take a decision to switch.
