1. **State the problem:** We are given body temperatures recorded at 8 AM and 12 AM for five subjects or days. We need to determine if there is a meaningful way to match each 8 AM temperature with the corresponding 12 AM temperature. 2. **Analyze the data:** The table shows temperatures: | Subject/Day | 1 | 2 | 3 | 4 | 5 | |-------------|-----|-----|-----|-----|-----| | 8 AM | 97.0| 98.5| 97.6| 97.7| 98.7| | 12 AM | 97.6| 97.8| 98.0| 98.4| 98.4| 3. **Interpret the options:** - Option A says 8 AM temps are from one individual over five days and 12 AM temps from a different individual over the same days. - Option B says each column corresponds to the same subject, so each pair is matched. - Option C says 8 AM temps are from one individual over five days and 12 AM temps from another individual over five days. - Option D says 8 AM and 12 AM temps are from the same individual over five days, so each pair is matched. 4. **Important rule:** For paired data, each pair must correspond to the same subject or individual at different times. 5. **Evaluate the options:** - Option A implies different individuals, so no meaningful pairing. - Option B implies each column is a subject, so 8 AM and 12 AM temps in the same column are paired. - Option C implies different individuals, so no pairing. - Option D implies same individual over days, so pairing is meaningful. 6. **Conclusion:** Since the table columns are labeled 1 to 5, likely representing subjects, and each column has 8 AM and 12 AM temps, the best interpretation is Option B: each column corresponds to the same subject, so each pair is matched. **Final answer:** Option B.
