Answer:
There is likely to be a correlation and this correlation reflect a causal relationship
Step-by-step explanation:
If you have this two variables:
T: The average daily winter temperature (°F)
H: heating bill ($)
you can notice that when the average daily winter temperature decreases you must increase the heating energy and that leads to heating bill increases to.
Therefore you can say that when the temperature decreases, the heating bill increases.
This two variables have a negative correlation (the value of one variable increases, the other decreases).
and there is a causal relationship because if the occurrence of the first causes the other. In this case The average daily winter temperature event is called the cause and the heating bill event is called the effect.
