Refer to the table of body temperatures (degrees Fahrenheit). Is there a meaningful way in which each body temperature recorded at 8 AM is matched with the 12 AM temperature?

| Subject | 8 AM | 12 AM |
|---------|------|-------|
| 1 | 97.0 | 97.6 |
| 2 | 98.5 | 97.8 |
| 3 | 97.6 | 98.0 |
| 4 | 97.7 | 98.4 |
| 5 | 98.7 | 98.4 |

Choose the correct answer below:

A. No. The 8 AM temperatures are from one individual over five days, and the 12 AM temperatures are from another individual over five days.

B. Yes. 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.

C. Yes. Each column of 8 AM and 12 AM temperatures is recorded from the same subject, so each pair is matched.

D. Yes. 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.

Answer :

Answer:

C

Step-by-step explanation:

i just did that question and got it right!!

Final answer:

The correct answer is C, indicating that the 8 AM and 12 AM body temperatures are recorded from the same subject and are therefore matched for comparison.

Explanation:

Based on the information provided, the correct answer to the question regarding the relationship between 8 AM and 12 AM body temperatures is C. Yes. Each column of 8 AM and 12 AM temperatures is recorded from the same subject, so each pair is matched. This means that for a given subject, their temperature at 8 AM on a specific day is directly compared to their temperature at 12 AM on the same day. Understanding this pairing is crucial for studying circadian changes in body temperature, as body temperature naturally fluctuates throughout the day, with typical patterns showing rises throughout the waking hours and falls during sleep, reaching the lowest point in the very early morning hours.
