7. The data set epoxy .txt contains data from an experiment to determine the effect of the level of epoxy in an automotive paint formulation. The response considered is the appearance measure longwave (LW). Consider the function (3.3.11) to model this set of data, where Y = LW and x = epoxy level in the formulation.

(a) Make two scatter plots of the data to assess the suitability of the model. Make one plot of the original data and a second after the data have been transformed.

(b) Use least squares to find the parameter estimates and report the fitted model.

(c) Predict the LW reading for a paint with an epoxy level of 1.25.
