The U.S. population in selected years between 1815 and 1965 is listed in the table below. Determine a quadratic equation in the form P= ar + at +ap, where tis the number of years after 1800 and Pis the population millions, that best fits the data. Use the equation to estimate the population in 1915 (the population was 98.8 millions). Make a plot of the population versus the year that shows the data points and the equation. Year 1815 1845 1875 1905 1935 1965 190.9 Population (millions) 8.3 19.7 44.4 83.2 127.1
