The following four scatterplots pertain to a study that investigated predicting the price of a wine based on its age and three variables associated with the weather during the year in which it was produced: summer temperature, winter rain, and harvest rain:
A:
B:
C:
D:
Consider the following five correlation values. Four of them are calculated from these scatterplots, and the fifth does not apply to any of these graphs. For each correlation value, you are either to identify the graph that it is calculated from or say that it does not apply to any of these graphs.
1. -.750
2. -.449
3. .234
4. .452
5. .589
