Given the following null and alternative hypotheses, complete parts a and b. \mathrm{H}_{0}: \sigma^{2}=100 H_{A}: \sigma^{2} \neq 100 a. Test whenn=26, s = 9, and a = 0.10. Be certain to state the decision rule. \text { If the test statistic, } \chi^{2}<\chi_{1}^{2}-\alpha=\square \text {, reject } \mathrm{H}_{0} \text {. }
