The Index of Exposure to Radioactive Waste and the Cancer

Essay

The index of exposure to radioactive waste and the cancer mortality rates (deaths per 100,000)were recorded for nine different geographic regions.Using a 1% level of significance,use the regression analysis provided below to perform the hypothesis test to determine if the index of exposure is useful as a predictor or cancer mortality rate.
Dependent variable is: Cancer Mortality Rate
R-squared = 85.8%
s = 14.00993 with 9 - 2 = 7 degrees of freedom $$\begin{array} { l l l l l } \text { Variable } & \text { Coefficient } & \text { SE(Coeff) } & \text { t-ratio } & \text { P-value } \\\text { Constant } & 114.7156 & 8.045663 & 14.25807 & 0.00000198 \\\text { Index of Exp } & 9.231456 & 1.418787 & 6.506584 & 0.000332\end{array}$$
