EXAMPLE 4.7
A census of the population of the United Kingdom is taken every 10 years The
foowing data list the population, in thousands on people, from 1930 to 1990
1930 – 123 203; 1940 - 131 669; 1950 - 150 697; 1960 - 179 323;
1970 - 203 212; 1980 - 226 505; 1990 - 249 633.
Find the population in 1965 from the polynomial that interpolates the data.
