IN MATLAB. Please do not change variable name. 

The U.S. population in selected years between 1815 and 1965 is listed in the table below. Determine
quadratic equation in the form
P = azt? + ajt + ap, where tis the number of years after 1800 and Pis the population in 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.
