11.62 Olajossy, Gawdzik, Budner, and Dula (Trans IchemE, 2003) conducted an experiment of plant output and recorded the ratio of recycled methane to feed methane. They also recorded the product purity (vol. %) and efficiency of methane recovery

(%). The data are given in the table below.

a Make scatterplots of the recycled ratio, product purity, and efficiency of recovery versus the plant capacity.
b Describe the nature of each relation in context.

c Estimate each relation using an appropriate model.
d Because all three variables provide outcomes of the same experiments, comment on their behavior collectively in the context of the problem.
