The output below is from a multiple linear regression of surface finish on cutting RPM and cutting bit type, where bit type is a categorical variable taking values A,B,C, or D. To run the regression, indicators have been generated for bit types B, C, and D, e.g., if the bit is of type B then the indicator for B will take value 1 and all others will take value 0. Based on the analysis - what is the expected surface finished when the RPMs equal 250 and the bit used is of type A (please round your answer to the closest 10th, i.e., the first decimal place) SUMMARY OUTPUT Regression Statistics Multiple R R Square Adjusted R Square Standard Error Observations 0.994 0.989 0.987 1.089 35 ANOVA df SS MS F Significance F 0.000 4 3178 794 670 Regression Residual Total 30 1 36 3213 34 Lower 95% Intercept RPM Type B Type C Type D Coefficients 24.49 0.10 -13.31 -20.49 -26.04 Standard Error 2.47 0.01 0.49 t Stat P-value 9.90 0.0000 9.40 0.0000 -27.32 0.0000 -42.06 0.0000 -43.62 0.0000 19.44 0.08 -14.31 Upper 95% 29.55 0.12 -12.32 -19.49 -24.82 0.49 -21.48 -27.26 0.60
