Question

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 0.74. 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? it is a weak positive correlation, and it is not likely causal. it is a weak positive correlation, and it is likely causal. it is a strong positive correlation, and it is not likely causal. it is a strong positive correlation, and it is likely causal.

Explanation:

• Correlation coefficient \(r = 0.74\). Since \(0.74>0.7\), it is a strong positive correlation.
• Just because there is a correlation between sodium and calories does not mean there is causation. There could be other factors (e.g., type of cuisine, preparation methods) that influence both.

Answer:

It is a strong positive correlation, and it is not likely causal.
