A conservation biologist wants to investigate if there is a relationship between the average ambient temperature during the nesting season and the hatching success rate of green sea turtle clutches.
The biologist monitors 12 nests on a tropical beach. For each nest, they record:
The raw data collected in the study are shown in Table 1 below.
Table 1 Mean sand temperature and hatching success rate for 12 nests

| 3 | 29.0 | 85 |
| 4 | 32.1 | 48 |
