Question: 29
14. Which sample would be the most appropriate participants for a study on hormone replacement therapy for postmenopausal symptoms?
- A. Prepubescent girls
- B. Premenopausal adult women
- C. Pregnant women
- D. Postmenopausal women
Correct Answer: D
Explanation:
Samples should always be taken from the target population or population of interest. Given that the target population is postmenopausal women, this group should be used for the sample. Both prepubescent girls and pregnant women are populations with special precautions against coercion, and are not appropriate for this study, eliminating choices (A) and (C). Premenopausal women are unlikely to require hormone replacement therapy unless they have a condition that specifically necessitates it, eliminating choice (B).
