A highway employee performed a regression analysis of the relationship between the number of
construction work-zone fatalities and the number of unemployed people in a state. The regression equation
is Fatalities = 12.7 + 0.000114 (Unemp). Some additional output is: Predictor Coef SE Coef T P
Constant 12.726 8.115 1.57 0.134
Unemp 0.00011386 000002896 3.93 0.001
Analysis of Variance Source DF SS MS F P
Regression 1 10354 10354 15.46 0.001
Residual Error 18 12054 670 Total 19 22408
