The following data represent the calories and fat, in grams, of various 16 -ounce a. Compute the covariance. iced coffee drinks. (Round to three decimal places as needed.) b. Compute the coefficient of correlation. (Round to three decimal places as needed.) c. Which do you think is more valuable in expressing the relationship between calories and fat-the covariance or the coefficient of correlation? Explain. Use the data above to complete parts (a) through (d). A. The correlation is more valuable. It can be used to determine the relative strength of a linear relationship. B. The correlation is more valuable. It is the better measure for positive relationships. c. The covariance is more valuable. It is an exact measure of the strength of a linear relationship. d. What conclusions can you reach about the relationship between calories and fat? A. The covariance shows a very strong positive relationship. If calories increase, so will fat. B. The covariance indicates a large variance in both calories and fat. C. The correlation shows a nearly perfect positive relationship. D. The correlation indicates a moderate positive relationship. As calories increase, fat tends to increase
