Question

2. The followving data give the drying time T of a certain pauin n t a certain additive A. Find the first, second, third, and fourth-degree polynomials that fit the data and plot each polynomial with the data. Set limits O and 10 on the x-axis and a function of the amount 10 on the x-axis and limits 0 and 150 on the y-axis. Determine the quality of the curve fit for each by computing J Note: You have to use for-loops to perform the above, Any other form of solution will not be given credit.
