Click a question to see the answer.

1. What usually causes #NUM! in =CONFIDENCE.NORM?

A. Requires add-in
B. If alpha ≤ 0 or alpha ≥ 1, CONFIDENCE.NORM returns the #NUM! error value. If standard_dev ≤ 0, CONFIDENCE.NORM returns the #NUM! error value. If size < 1, CONFIDENCE.NORM returns the #NUM! error value. ✓
C. Output is always a dynamic array
D. Only works in old versions

Explanation: If alpha ≤ 0 or alpha ≥ 1, CONFIDENCE.NORM returns the #NUM! error value. If standard_dev ≤ 0, CONFIDENCE.NORM returns the #NUM! error value. If size < 1, CONFIDENCE.NORM returns the #NUM! error value. — Fix: Correct the input value

2. In =CONFIDENCE.NORM, which is argument #3?

A. alpha
B. size ✓
C. value
D. lookup_value

Explanation: Argument #3 is “size”.

3. What is the fix for #VALUE! in =CONFIDENCE.NORM?

A. برای هر سه آرگومان مقدار عددی وارد کنید. ✓
B. Volatile and recalculates every time
C. Only works in old versions
D. آلفا خارج از ‎۰ تا ۱، انحراف معیار صفر/منفی یا حجم نمونه کمتر از ‎۱ است.

Explanation: If any argument is nonnumeric, CONFIDENCE.NORM returns the #VALUE! error value. — Fix: برای هر سه آرگومان مقدار عددی وارد کنید.

4. In =CONFIDENCE.NORM, which is argument #1?

Explanation: Type of “standard_dev” is “Number”.

14. Which statement about =CONFIDENCE.NORM is correct?

A. If size is not an integer, it is truncated. ✓
B. Requires add-in
C. Output is always a dynamic array
D. If we assume alpha equals 0.05, we need to calculate the area under the standard normal curve that equals (1 - alpha), or 95 percent. This value is ± 1.96. The confidence interval is therefore:

Explanation: Correct: If size is not an integer, it is truncated.
