Reconsider the jet turbine engine thrust data in Table B.13. Use stepwise regression to find an appropriate regression model for these data. Investigate model adequacy using residual plots. Compare this model with the one found by the all-possible-regressions approach in Problem 10.21.

Data From Problem 10.21

Table B. 13 presents data on the thrust of a jet turbine engine and six candidate regressors. Use all possible regressions and the Cp${\mathrm{????}}_{\mathrm{????}}$ criterion to find an appropriate regression model for these data. Investigate model adequacy using residual plots.
