Question

QUESTION 1 A type Il error occurs if we fail to reject the null hypothesis when it is false. True False QUESTION 2

Answer 1

The correct option is True. [ANSWER]

Explanation:

In a hypothesis test there are 4 possible events which are shown in the following table:

		H0 is
		TRUE	FALSE
Decision	Reject H0	Type I error	Correct Decision
	Do no reject H0	Correct Decision	Type II error

From the table above it is clear that a Type I error occurs when we reject a correct null hypothesis.

A Type II error occurs when we fail to reject a false null hypothesis.

In the other two cases, namely, rejecting a false null hypothesis and not rejecting a correct null hypothesis, the decision is correct.
