Dr. Aris is conducting an investigation into whether there is a relationship between the ambient room temperature of an office and the productivity of its workers. He recorded the daily average ambient temperature (in degrees Celsius) and the productivity score (measured on a standardized scale from 1 to 50) of eight office employees over a working day.
Table 1 shows the data Dr. Aris collected.
Table 1:
| Participant | Daily average ambient temperature (°C) | Productivity score (1–50) |
|---|---|---|
| Participant 1 | 16.5 | 44 |
| Participant 2 | 18.2 | 41 |
| Participant 3 | 20.1 | 37 |
| Participant 4 | 22.0 | 32 |
| Participant 5 | 24.3 | 28 |
| Participant 6 | 26.5 | 20 |
