Question

Also known as beta error, _________ occurs when the sample results lead to the nonrejection of a null hypothesis that is in fact false.

• A. type I error
• B. two-tailed error
• C. type II error
• D. one-tailed error

Hint:

Type I = “false positive”; Type II = “false negative.”

Answer 1

The Correct Option is C

Step 1: Error definitions.
Type I error ($\alpha$): Rejecting $H_0$ when $H_0$ is actually true.
Type II error ($\beta$): Failing to reject $H_0$ when $H_0$ is actually false.
Step 2: Matching to the stem.
The stem says “nonrejection of $H_0$ that is false” — this is Type II error (also called beta error). \[ \boxed{(c)} \]
