2.15 Byers and Williams ("Viscosities of Binary and Ternary Mixtures of Polynomatic Hydrocarbons," Journal of Chemical and Engineering Data, 32, 349354, 1987) studied the impact of temperature on the viscosity of toluene-tetralin blends. The following table gives the data for blends with a 0.4 molar fraction of toluene. a. Estimate the prediction equation. b. Perform a complete analysis of the model. c. Calculate and plot the 95% confidence and prediction bands. Temperature Viscosity (C) (mPas) 24.9 1.1330 35.0 0.9772 44.9 0.8532 55.1 0.7550 65.2 0.6723 75.2 0.6021 85.2 0.5420 95.2 0.5074
