Multiple Choice

Refer to the following regression results. The dependent variable is Abort (the number of abortions per 1000 women of childbearing age) . The regression was estimated using data for the 50 U.S. states with these predictors: EdSpend = public K-12 school expenditure per capita, Age = median age of population, Unmar = percent of total births by unmarried women, Infmor = infant mortality rate in deaths per 1000 live births. $$\begin{array} { l r r r } \hline \text { Variable } & \text { Coefficients } & \text { Standard Error } & t - \text { Stat } \\\hline \text { Intercept } & - 19.244 & 25.387 & - 0.758 \\\text { EdSpend } & 0.0080040 & 0.0054472 & 1.469 \\\text { Age } & 0.76012 & 0.66914 & 1.136 \\\text { Unmar } & 0.98629 & 0.22132 & 4.456 \\\text { InfMor } & - 3.7848 & 1.0173 & - 3.720 \\\hline\end{array}$$ Which statement is not supported by a two-tailed test?

• A)Unmar is a significant predictor at ? = .01.
• B)EdSpend is a significant predictor at ? = .20.
• C)Infmor is not a significant predictor at ? = .05.
• D)Age is not a significant predictor at ? = .05.
