hw08 ChE 132C due Mar. 11 , 2011 1) Think critically about the meaning of your model, even if the p-value is tiny! Pacansky et al. Appl. Spectr. 40, 9 (1986). Polyperflouropropyleneoxide (PPFPO) is a viscous liquid used in electronics as a lubricant. The optical density (y) of PPFPO was measured at different absorption band frequencies (x 1 ) of PPFPO with different film thicknesses (x 2 ). The data are a) Is this experiment designed such that nonlinear effects between thickness and frequency would be detected (if they did exist)? b) Create a two variable linear regression model of the type y = 0 + 1 x 1 + 2 x 2 . The variable y is a degree of absorbance relative to some standard surface film, i.e. a non-negative number. Do the values predicted by your regression model make sense at each of the 12 data points? Circle those rows of the table for which the regression model predicts y-values that are
