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.\nwhich best describes the strength of the correlation, and what is true about the causation between sodium and the number of calories in this meal?\n○ it is a weak positive correlation, and it is not likely causal.\n○ it is a weak positive correlation, and it is likely causal.\n○ it is a strong positive correlation,and it is not likely causal.\n○ it is a strong positive correlation, and it is likely causal.

Answer

Brief Explanations:

  1. Correlation coefficients range from -1 to 1. A value close to 1 (like 0.74) indicates a strong positive correlation.
  2. Zero-calorie sodium has no caloric content, so it cannot directly cause an increase in the meal's total calories. Any correlation is likely due to a third factor (e.g., both sodium and calorie-dense ingredients being used in the same meal type), not direct causation.

Answer:

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