Eight Milligrams of a Dye Are Injected into a Vein $n=12$

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 $R=\frac{60 D}{\int_{0}^{24} C(t) d t}$ 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.
