उत्तर
In statistical hypothesis testing, a type f error is the rejection of a true null hypothesis.
Example of type I errors includes a test that shows a patient to have a disease when he does not have the disease, a fire alarm going on indicating a fire when there is no fire or an experiment indicating that medical treatment should cure a disease when in fact it does not.
