7) The weight (in pounds) and amps for 19 circular saws was collected. Saws with higher amp ratings tend to also be heavier than saws with lower amp ratings. This fact was quantified using regression with the following output: SUMMARY OUTPUT Regression Statistics Multiple R 0.6761 R Square 0.4571 Adjusted R Square 0.4252 Standard Error 0.7822 Observations 19 ANOVA of SS MS F Significance F Regression 8.7579 8.7579 14.3158 0.0015 Residual 17 10.4000 0.6118 Total 18 19.1579 Coefficients Standard Error P-value Lower 95% Upper 95% Intercept 5.8000 .4412 4.0244 0.0009 2.7593 8.8407 Amps 0.4000 0. 1057 3.7836 0.0015 0.1770 0.6230 a.
