The following data give the drying time T of a certain paint as a function of the amount of a certain additive A. a. Find the first-, second-, third-, and fourth-degree polynomials that fit the data, and plot each polynomial with the data. Determine the quality of the curve fit for each by computing J, S, and r^2.
b. Use the polynomial giving the best fit to estimate the amount of additive that minimizes the drying time.

A (oz) 0 1 2 3 4 5 6 7 8
T (min) 130 115 110 90 89 89 95 110 125
