Independent check: new record
Independent task · New record
Four additional fresh 120 g trials;40.0°C start;22°C surroundings;15 min;sleeve versions/cups/lids/exposure/procedure match the first independent-task record. Accuracy remains unknown. Covered liquid water; no active heating/cooling, ice, phase change, direct sunlight or meaningful evaporative cooling. Room, cup, lid and supporting surfaces are at the stated surrounding temperature; it stays constant. Readings represent the sample temperature with a consistent procedure. This is a paper scenario, not apparatus instructions.
New paired endpoints
Constructed teaching data: these values were invented for this activity, not collected in an experiment.
Trial ID | Cover P final (°C) | Cover Q final (°C) |
|---|---|---|
I-3 | 34.7 | 35.0 |
I-4 | 35.1 | 34.9 |
I-5 | 34.9 | 35.0 |
I-6 | 35.0 | 35.1 |
1. Using all six trials, decide whether to retain, narrow, change or remain uncertain. Give a revised claim and specific comparisons, including any contrary result.

2. What useful next evidence would address the uncertainty? Does overlap establish identical performance? Does the newest row alone decide?
