The following data represent the calories and fat, in grams, of various 16-ounce iced coffee drinks. a. Compute the sample covariance. (Round to three decimal places as needed.) Product Calories Fat 240 9.0 b. Compute the coefficient of correlation. 290 3.9 350 22.0 380 21.7 (Round to three decimal places as needed.) 490 17,7 c. Which do you think is more valuable in expressing the relationship between calories and fat-the covariance or the coefficient of correlation? Explain. F 520 20.4 G 600 19.5 O A. The correlation is more valuable. It can be used to determine the relative strength of a linear relationship. Use the data above to complete parts (a) to (d) O B. The correlation is more valuable. It is the better measure for positive relationships. O C. The covariance is more valuable. It is an exact measure of the strength of a linear relationship.
