Final answer:
None of the options presented in the question (a, b, c, d) are accurate since three out of the four statements given contain contradictions about age ranges that cannot be true. Only Statement D could be potentially true, as it is the only one that aligns with the criteria of being under 30 years old.
Step-by-step explanation:
The student's question pertains to interpreting statements about percentages of individuals within certain age ranges. On analysis of the given scenarios:
- Statement A suggests that 25% of people under 30 years old are actually between 27 and 30 years old. This is contradictory because if they are under 30, they cannot also be over 27, encompassing 30 within that range.
- Statement B implies that 50% of people above 30 years are between 27 and 30. This cannot be correct as those above 30 cannot be in the 27 to 30 age range.
- Statement C indicates that 25% of people over 30 are between 16 and 27 years old, which is impossible as these ages are less than 30.
- Statement D states that 50% of those under 30 are between 5 and 18 years old, which could be correct because these ages are within the range of being under 30.
Based on the analysis, none of the options (a, b, c, d) is entirely correct because Statement D is the only one that could possibly be true. Hence, we cannot confirm any of the presented options as being correct without additional information.
