CompTIA DataX (DY0-001) — Question 82

Which of the following distributions would be best to use for hypothesis testing on a data set with 20 observations?

Answer options

• A. Power law
• B. Normal
• C. Uniform
• D. Student's t-

Correct answer: D

Explanation

The Student's t-distribution is ideal for hypothesis testing with small sample sizes, such as 20 observations, because it accounts for increased variability. In contrast, the Normal distribution is more suitable for larger samples, while the Power law and Uniform distributions do not provide appropriate models for the context of hypothesis testing in this scenario.
