The Index of Exposure to Radioactive Waste and the Cancer

Multiple Choice

The index of exposure to radioactive waste and the cancer mortality rates (deaths per 100,000) were recorded for nine different geographic regions. Dependent variable is: Cancer Mortality Rate
R-squared = 85.8%
S = 14.00993 with 9 - 2 = 7 degrees of freedom $$\begin{array} { l l l l l } \text { Variable } & \text { Coefficient } & \text { SE(Coeff) } & \text { t-ratio } & \text { P-value } \\\text { Constant } & 114.7156 & 8.045663 & 14.25807 & 0.00000198 \\\text { Index of Exp } & 9.231456 & 1.418787 & 6.506584 & 0.000332\end{array}$$

A) Cancer Mortality Rate = 114.7156 + 9.231456 × Index of Exp; The cancer mortality rates in these counties increase by about 9.231456 deaths per 100,000 for each 1 point increase in the index of exposure to radioactive waste.
B) Cancer Mortality Rate = 114.7156 + 9.231456 × Index of Exp; The cancer mortality rates in these counties increase by about 114.7156 deaths per 100,000 for each 1 point increase in the index of exposure to radioactive waste.
C) Cancer Mortality Rate = 114.7156 × Index of Exp + 9.231456; The cancer mortality rates in these counties increase by about 114.7156 deaths per 100,000 for each 1 point increase in the index of exposure to radioactive waste.
D) Cancer Mortality Rate = 114.7156 × Index of Exp + 9.231456; The cancer mortality rates in these counties increase by about 9.231456 deaths per 100,000 for each 1 point increase in the index of exposure to radioactive waste.
E) Index of Exp = 114.7156 + 9.231456 × Cancer Mortality Rate; The index of exposure to radioactive waste in these counties increases by about 9.231456 points for every 1 death per 100,000 increase in the cancer mortality rate.
