C)3.325
D)2.180
E)23.589

The chi-square distribution table or calculator indicates that with 9 degrees of freedom (df = 9) and a significance level of 5% (α = 0.05), the critical value for the lower tail (probability of getting a result less than a certain value) is not typically sought after, as chi-square tests usually look for values in the upper tail to reject the null hypothesis. However, the value closest to representing a lower bound in common tables or interpretations for a 5% level in the context provided, considering typical use and misunderstanding of the question's intent, would be none of the provided options. The correct answer should reflect an upper tail critical value for a chi-square distribution with 9 df at a 5% significance level, which is not accurately represented here for a lower bound scenario. This question seems to have a misunderstanding in its formulation regarding how chi-square distributions and their critical values are typically applied.
