[EX03-059] What is the relationship between carbohydrates consumed and energy released in a sports drink? Did you ever wonder if there was a relationship? Let’s use the sports drink data listed in Exercise 3.43 on page 171 to investigate the relationship.

a. In Exercise 3.43 a scatter diagram was drawn using x  carbs/serving and y  energy/serving.

Review the scatter diagram (if you did not draw it before, do so now), and describe why you believe there is or is not a linear relationship.

b. Find the equation for the line of best fit.

c. Using the equation found in part

b, estimate the amount of energy that one can expect to gain from consuming 40 grams of carbohydrates.

d. Using the equation found in part

b, estimate the amount of energy that one can expect to gain from consuming 65 grams of carbohydrates.
