Chapter 8, Problem 25P
Use the growth data from Problem 24 for the following:
(a) Curve-fit the data with a third-order polynomial. Use the polynomial to estimate the height in day 40.
(b) Fit the data with linear and spline interpolations and use each interpolation to estimate the height in day 40.
In each part make a plot of the data points (circle markers) and the fitted curve or the interpolated curves. Note that part (b) has two interpolation curves.
