The index of exposure to radioactive waste, x, and the cancer mortality rates, y, (deaths per 100,000) were recorded for nine different Oregon counties. Use the regression analysis provided below to perform the hypothesis test to determine if the index of exposure is useful as a predictor of cancer mortality rate. The regression equation is = 114.7156 + 9.231456x R-sq = 85.8% 9- 2 = 7 degrees of freedom Predictor Coef Constant 114.7156 Index of Exp 9.231456 SE(Coef) I 8.045663...
