10. Why does the two-sided t-test table include only the upper half of the data (p from 0.5 to 0.001) and the chi-square probability table include the entire range (p from .995 to .005)?

11. In the confidence interval equation $\overline{x} \pm t_{\alpha,\nu}*\frac{s_{x}}{\sqrt{n}}$ , what does $\frac{s_{x}}{\sqrt{n}}\ $represent?
