(a) Determine and plot the degree 10 Lagrange polynomial through the data. Use it
to estimate the 2010 cost and compare to the actual value of $1,049 (in mil.).
(b) Determine and plot a clamped cubic spline for the data (using the appropriate
slopes at 2005 and 2016). Use it to estimate the 2010 cost and compare to the
actual value of $1,049 (in mil.)
1
(c) Perform a least-squares analysis and estimate the 2010 cost and compare to the
actual value of $1,049 (in mil). (Choose an appropriate least squares linear or
polynomial model.)
