Eight milligrams of a dye are injected into a vein leading the an individual’s heart. The concentration of dye in the aorta (in milligrams per liter) measured at 2-sec intervals is shown in the accompanying table. Use Simpson’s Rule with n=12 and the formula 
to estimate the person’s cardiac output, where D is the quantity of dye injected in milligrams, C(t) is the concentration of the dye in the aorta, and R is measured in liters per minute. Round to one decimal place.
