Question

the table shows the number of calories in four meals and the cost of each meal. which best describes the strength of the model? cost of meal and number of calories number of calories in the meal cost of the meal 550 $12 1,250 $11 780 $13 650 $10 a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation

Explanation:

Step1: Analyze the data trend

As the number of calories (550, 1250, 780, 650) does not show a clear - cut increasing or decreasing pattern with respect to the cost of the meal ($12, $11, $13, $10), there is no strong linear relationship.

Step2: Determine the correlation type

Since there is no clear upward or downward trend, the correlation is weak. Also, there is no consistent increase or decrease in one variable as the other variable changes, so it is not a positive or negative correlation in a strong sense. But looking at the data points, there is no obvious negative relationship either. So we can say it is a weak positive or negative correlation. Since the data is so scattered, we lean towards a weak correlation. And as there is no clear negative trend, we say it is a weak positive correlation.

Answer:

a weak positive correlation
