Question 5 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY
The number of grams of zero-calorie sodium in a restaurant meal is compared to the total number of calories in the meal. The correlation coefficient relating the two variables is 0 point 7 4 Which best describes the strength of the correlation, and what is true about the causation between sodium and the number of calories in this meal?
Answer
A
It is a strong positive correlation, and it is likely causal.
B
It is a strong positive correlation, and it is not likely causal.
C
It is a weak positive correlation, and it is not likely causal.
D
It is a weak positive correlation, and it is likely causal.
Explanation
A correlation coefficient of 0.74 is positive and fairly close to 1, so it indicates a strong positive correlation. This association does not show that sodium causes the meal’s calorie count; other factors, such as portion size or ingredients, could affect both. So the best choice is “a strong positive correlation, and it is not likely causal.”
