Hsuie, Ma, and Tsai (Separation and Characterizations of Thermotropic Copolyesters of p-Hydroxybenzoic Acid, Sebacic Acid, and Hydroquinone,
Question:
Hsuie, Ma, and Tsai (‘‘Separation and Characterizations of Thermotropic Copolyesters of p-Hydroxybenzoic Acid, Sebacic Acid, and Hydroquinone,’’ (1995, Vol. 56) studied the effect of the molar ratio of sebacic acid (the regressor) on the intrinsic viscosity of copolyesters (the response). The following display presents the data.
Ratio Viscosity
1.0.................................0.45
0.9.................................0.20
0.8.................................0.34
0.7.................................0.58
0.6.................................0.70
0.5.................................0.57
0.4.................................0.55
0.3.................................0.44
(a) Construct a scatterplot of the data.
(b) Fit a second-order prediction equation.
Step by Step Answer:
a b To fit a second order model the ratio term is squared intercept ra...View the full answer
