Subsequent data indicated that life expectancy grew to 73.2 years for males born during 1995-2000 and to 74.3 years for males born during 2000-2005. Add the points (15,73.2) and (20,74.3) to the data set in Problem 84. Use a graphing calculator to find a quadratic regression model for all five data points. Graph the data and the model in the same viewing window.
