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.

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

Step-by-step explanation: Correlation Coefficient value is used to determine the strength of linear relationship between two variables. The value ranges from - 1 to +1.with negative values depicting a negative relationship and positive values showing positive relationship. Value of 0 implies that, no relationship exists. The closer the correlation Coefficient value is to +1 or - 1, the greater the strength of the relationship between them. Also correlation does not mean causation. Hence, a correlation coefficient of 0.74 depicts a strong positive relationship. However it doesn't imply causation.
