What is called as the rejection probability of null hypothesis when it is true?

Significance level [ alpha ] The probability of rejecting the null hypothesis when it is true. alpha = 0.05 and alpha = 0.01 are common. If no level of significance is given, use alpha = 0.05. The level of significance is the complement of the level of confidence in estimation.

When the hypotheses is true but we reject it is known as?

If we reject a true null hypothesis, we have committed a type I error. If we accept a false null hypothesis, we have made a type II error. Each of these four possibilities has some probability of occurring, and those probabilities depend on whether the null hypothesis is true or false.

What is assumed to be true in a hypothesis test?

The null hypothesis states the "status quo". This hypothesis is assumed to be true until there is evidence to suggest otherwise.

What does it mean when a hypothesis is rejected?

After a performing a test, scientists can: Reject the null hypothesis [meaning there is a definite, consequential relationship between the two phenomena], or. Fail to reject the null hypothesis [meaning the test has not identified a consequential relationship between the two phenomena]
