Extracted text: Question 34 $2.5 \mathrm{pts)$ The following samples are independently selected from two populations which follow the normal distributions with equal variance. \begin{tabular}{]l|1|} \hline Sample 1 & Sample 2 \\ \hline$n_{1)=10$ & $n_{2)=12s \\ \hline $\bar{x}_{1)=20$ & $\bar{x}_{2}=18$ \\ \hline$s_{1)=5$ & $s_{2}=4.5$ \\ \hline \end{tabular} One wishes to test the following hypotheses. SH_{0): \mu_{1}-\mu_{2}=0 \quad H_{a): \mu_{1}-\mu_{2)>0$ Find the rejection region for the above test with significance level of .05. SP.DL.239|
