Extracted text: 20.1 Find two tables of data in an engineering textbook or engineering website. Plot each (with '** at data points) and decide if the data is best represented by a polynomial interpolant, spline interpolant, or least squares fit polynomial. Label the axes and include a title. Turn in the best plot of each. Indicate the source and meaning of the data.
