The accompanying data resulted from an investigation of the relationship between temperature and viscosity for specimens of bitumen removed from tar sand deposits

x:750,800,700,850,590,620,650,680,710,550

y:50,16,102,10,945,818,403,151,114,1358

a) Would a straight-line fit to this data give accurate predictions of viscosity?

b) Fit a straight line to the (ln(x),ln(y)) data, use it as a basis for predicting viscosity when temperature is 720, and calculate a quantitative assessment of the extent to which the approximate linear relationship between lnx and lny explains ovserved variation.
