Diagnostic Test Rejection Region

It is the area in the normal curve that leads to rejection of null hypothesis.

• Acceptance Region

• Degrees of freedom

• Rejection region

• Type II Error

What kind of test is shown in this figure?

• Left-tailed Test

• No-tailed Test

• Right-tailed Test

• Two-tailed Test

What kind of test is shown in this figure?

• Left-tailed Test

• No-tailed Test

• Right-tailed Test

• Two-tailed Test

What kind of test is shown in this figure?

• Left-tailed Test

• No-tailed Test

• Right-tailed Test

• Two-tailed Test

In a right-tailed test with α = 0.01, the critical value of z is:

• 1.28

• 1.65

• 1.96

• 2.33

Given the normal curve, what is the rejection region?

• z ≤ 1.645 or z ≥ 1.645

• z ≥ −1.645 or z ≥ 1.645

• z ≥ −1.96 or z ≤ 1.96

• z ≤ −1.96 or z ≥ 1.96

In a given problem, the _________ and the type of test (one-tailed or two-tailed) will set the rejection region (critical region) of the null hypothesis.

• level of confidence

• level of significance

• level of rejection

• level of acceptance
