Really really lost

An article describes an experiment in which nine steel specimens were submerged in seawater at various temperatures and the corrosion rates were measured. The results are presented in the following table Temperature Corrosion (C) (mm/yr) 26.6 1.58 26 1.45 27.4 1.13 21.7 0.96 14.9 0.99 11.3 1.05 15 0.82 8.7 0.68 8.2 0.47 Note that these are the same data as for a previous question, so you may just continue your work with this question. Complete the table by computing the fitted values and the residuals. Predicted y for given of residual 26.6 1.58 26 1.45 27.4 1.13 21.7 0.96 14.9 0.99 11.3 1.05 15 0.82 8.7 0.68 8.2 0.47
