Carbohydrates (in grams) can be used to predict the amount of energy released by a sports drink
(in kilocalories). In a study of several sports drink the mean carbohydrates was 51.92 grams with
a standard deviation of 11.64 grams and the mean energy released was 179.51 kilocalories with
a standard deviation of 42.95 kilocalories. The correlation between carbohydrates and energy
released was .92.
