Question

Which of the following is/are true?

		Type I and Type II error probabilities are complements
		Type I and Type II errors cannot both occur in one hypothesis test.
		Type I and Type II error probabilities are conditional probabilities.
		At least one of Type I or Type II errors must occur.

Answer 1

Answer #1

Answer:-

1)Type I and Type II errors cannot both occur in one hypothesis test

2)At least one of Type I or Type II errors must occur.

Definition:

Type I : type I error is the rejection of a true null hypothesis.

Type II : type II error is the non-rejection of a false null hypothesis

The notion of Type I and Type II Errors is very important in hypothesis testing. The Ho/Ha should be set up such that a Type I Error is more serious than a Type II Error. A common example used to discuss Type I and Type II errors is the example of a trial in the US. Under US law, a defendant is considered "innocent until proven guilty." You could set up this hypothesis test as follows: Ho: defendent is...

Which of the following is a TRUE statement about hypothesis testing? The probability of a Type I error plus the probability of a Type II error always equals one. The power of a test concerns its ability to detect a null hypothesis. If there is sufficient evidence to reject a null hypothesis at the 5% level, then there is sufficient evidence to reject it at the 10% level. Whether to use a one-sided or a two-sided test is typically decided...
