Not rejecting the null hypothesis when its actually false C. Accepting the null hypothesis when its actually false D. Rejecting the alternative hypothesis it is actually falseConclusions True or false: The conclusion of “fail to reject the null hypothesis” has exactly the same meaning as “accept the null hypothesis.”
- True or False: A Type I Error is made by failing to reject the null hypothesis when the null hypothesis is actually incorrect.Ahypothesis test of a claim will be conducted. The null hypothesis is the following: “The car’s brakes are working normally.” a. Identify the Type I and Type II errors for the test. b. Specify which error has the greater consequence.if we do not reject the null hypothesis when the null hypothesis is in error, then we have made a a.Type β error b.Correct decision c.Type I error d.Type II error
