# In an experiment to determine the factors affecting tensile strength in steel plates, the tensilestrength (in kg/mm?), the manganese content (in parts per thousand), and the thickness (inmm) were measured for a sample of 20 plates. The following MINITAB output presents theresults of fitting the model Tensile strength = Bo + B1 Manganese + B2 Thickness.The regression equation isStrength = 26.641 + 3.3201 Manganese – 0.4249 ThicknessPredictorCoef StDevт РConstant26.6412.723409.78 0.000Manganese 3.32010.3319810.00 0.000Thickness -0.42490.12606 -3.37 0.004S = 0.8228 R-Sq = 86.2% R-Sq(adj) =84.6%Analysis of VarianceSS MS2 72.0136.005 53.190.000SourceDFRegressionResidual Error 1711.508 0.6769Total1983.517Predict the strength for a specimen that is 10 mm thick and contains 8.2 ppta.manganese.b.
