Answer :
To solve this question, we need to determine whether there is a meaningful way to match the body temperatures recorded at 8 AM with those recorded at 12 AM.
Let's analyze each option:
Option A:
- Statement: The 8 AM temperatures are from one individual over five days, and the 12 AM temperatures are from another individual over five days.
- Evaluation: If the temperatures are from different individuals, they might not have a direct, meaningful relationship. This option suggests there is no pairing based on the same subject.
Option B:
- Statement: The 8 AM temperatures are all from one individual over five days, and the 12 AM temperatures are from the same individual on the same five days, so each pair is matched.
- Evaluation: If both sets of temperatures are from the same individual on corresponding days, each 8 AM temperature can be directly compared to the 12 AM temperature on the same day. This suggests a meaningful way to match the temperatures.
Option C:
- Statement: The 8 AM temperatures are all from one individual over five days, and the 12 AM temperatures are from a different individual on the same five days, so each pair is matched.
- Evaluation: If the temperatures are from different individuals but on the same days, there is still no direct, meaningful relationship based on the same subject's temperature variations.
Option D:
- Statement: Each column of 8 AM and 12 AM temperatures is recorded from the same subject, so each pair is matched.
- Evaluation: This option indicates that each pair of temperatures (i.e., one 8 AM and the corresponding 12 AM temperature in the same column) is recorded from the same subject. This means each temperature is matched within the same individual.
Given our analysis, Option D correctly describes the relationship:
Option D. Each column of 8 AM and 12 AM temperatures is recorded from the same subject, so each pair is matched.
This provides a meaningful way to match 8 AM and 12 AM temperatures as they are from the same subject on the same day.
