d) There is a negative correlation between the two variables.
Explanation:
A correlation refers to the fact that two variables fluctuate together.
A correlation can be positive or negative:
- A positive correlation between two variables means that they fluctuate in parallel (both increase or both decrease)
- A negative correlation between two variables means that they fluctuate in opposite ways (one increases and other decreases)
In this example, the number of hot chocolates <u>increases</u> as temperature outside <u>decreases</u>. The variables that are correlated are the temperature and the number of hot chocolates sold.
Since one of the variables increases while the other decreases, we can conclude that there is a negative correlation between the two variables.
