Using the regression results shown in Table 11.14 on page 342 in the textbook, answer the following: Conduct a 2-sided 5-step significance test on the collective influence of the independent variables at Ξ± = .05. Conduct a 2-sided 5-step significance test for the individual coefficient for poverty rate at Ξ± = .05.

Conduct a 2-sided 5-step significance test for the individual coefficient for poverty rate at Ξ± = .05.
Use Table 5 in Appendix $B$ to find the critical value(s) for the alternative hypothesis, level of significance $\alpha,$ and sample sizes $n_{1}$ and $n_{2}$. Assume that the samples are random and independent, the populations are normally distributed, and that the population variances are (a) equal and (b) not equal. $$H_{a}: \mu_{1}<\mu_{2}, \alpha=0.10, n_{1}=30, n_{2}=32$$
