Final answer:
A positive correlation exists between French fries consumption and the risk of a heart attack.
Step-by-step explanation:
A positive correlation means that as the value of one variable increases, the value of the other variable also increases. In this case, the more French fries a person eats, the greater their risk of a heart attack. Therefore, the two variables, French fries consumption and risk of a heart attack, are positively correlated. It is important to note that correlation does not imply causation. In other words, eating more French fries does not necessarily cause a heart attack.
