Answer:
D. The test was a 50-item test
Step-by-step explanation:
→ He scored above 75% of his classmates, NOT 25%. Therefore A is not the right answer.
→ He passed the test because the 75th percentile is equivalent to 3rd or upper quartile. Therefore B is not the right answer.
→ His score is on the upper quartile, not below. C can't be the answer.
→ The 75% of a 50-item test is 37.5. Since 37.5 couldn't be a proper score, it was rounded off to 38. D can be the right answer in this question.
