Step 1
Step 2
(b) Ignoring the outlier, describe the relationship between the amount of rainfall and the number of hours of sunshine.
Answer
Ignoring the outlier point, there is a negative correlation between the amount of rainfall and the number of hours of sunshine. As the rainfall increases, the number of sunshine hours tends to decrease. This trend suggests that more rainfall is associated with fewer hours of sunshine.
Step 3
(c) Using the scatter graph, estimate the amount of rainfall in this town on this day.
Answer
For 7 hours of sunshine, we can estimate the amount of rainfall to be approximately 4 mm. This estimate can be derived from the scatter plot where the point corresponding to 7 hours of sunshine falls close to the 4 mm rainfall mark.
