The table shows the number of calories in four meals and the cost of each meal. A 2-column table with 4 rows. The first column is labeled number of calories in the meal with entries 550; 1,250' 780; 650. The second column is labeled cost of the meal (in dollars) with entries 12, 11, 13, 10. Which best describes the strength of the model? a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation

The correlation coefficient between the variables number of calories in four meals and the cost of each meal is weak negative correlation.

Step-by-step explanation:

The data for the number of calories in four meals and the cost of each meal is as follows:

Number of Calories     Cost of Meals

          550                              12

         1250                              11

          780                              13

          650                              10

Use the Excel function "CORREL(array1,array2)" to compute the correlation coefficient between the variables number of calories in four meals and the cost of each meal.

The correlation coefficient between the variables number of calories in four meals and the cost of each meal is -0.13.

The correlation coefficient between 0.00 to ±0.30 is considered as weak correlation coefficient.

The correlation value of -0.13 lies in the range 0 to -0.30. This implies that the correlation coefficient between the variables number of calories in four meals and the cost of each meal is weak negative correlation.
