Use the $t$-distribution table to find the critical value(s) for the indicated alternative hypotheses, level of significance $\alpha$, and sample sizes $n_{1}$ and $n_{2}$. Assume that the samples are random and independent, and the populations are normally distributed. Complete parts (a) and (b). $$H_{a}: \mu_{1} \neq \mu_{2}, \alpha=0.20, n_{1}=10, n_{2}=2$$
Click the icon to view the $t$-distribution table. (a) Find the critical value(s) assuming that the population variances are equal. $$-1.372,1.372$$ (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.) (b) Find the critical value(s) assuming that the population variances are not equal. $\square$ (Type an integer or decimal rounded to three decimal places as needed.
