A gardener records the number of hours of sunshine and the growth of 10 sunflower plants over a week. The scatter graph shows this information.
| Sunshine (hours) | Plant growth (cm) |
|---|---|
| 2 | 6 |
| 3 | 9 |
| 5 | 15 |
| 6 | 16 |
| 7 | 21 |
| 8 | 23 |
| 9 | 27 |
| 10 | 30 |
| 11 | 32 |
| 9.5 | 8 |
What type of correlation does the scatter graph show?
One of the points is an outlier. Write down the coordinates for this point.
On another day there were 4 hours of sunshine. Estimate the plant growth for this day.
