The population in millions of the United States from 1920 to 2000 can be tabulated as:Year1920 1930 1940 1950 1960 1970 1980 1990 2000Population 106.45 123.07 132.10 151.27 180.67 204.05 227.23 246.46 281.421. Use the Newton's interpolating polynomial to predict the population in 2000 and calculate therelative true error.(a) Use the quadratic polynomial based on the data from 1970, 1980, and 1990.(b) Use the 3rd-order polynomial based on the data from 1960, 1970, 1980, and 1990.(c) Plot the data
