Dr. Aris is investigating the relationship between daily occupational noise exposure (measured in decibels, dBA) and subjective stress levels (measured on a scale of 1 to 100, where 100 represents extreme stress) among a sample of industrial workshop employees.
The raw data from this study is shown in Table 1.
| Daily noise exposure (dBA) | Subjective stress level |
|---|---|
| 65 | 32 |
| 70 | 45 |
| 85 | 78 |
| 90 | 88 |
| 60 | 25 |
| 55 | 18 |
| 80 | 62 |
