\begin{tabular}{|l|l|l|l|l|l|l|l|l|l|} \hline Patient & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\ \hline Before Therapy (X) & 33 & 17 & 30 & 25 & 36 & 25 & 31 & 20 & 18 \\ \hline After Therapy (Y) & 21 & 17 & 22 & 13 & 33 & 20 & 19 & 13 & 9 \\ \hline \end{tabular} We wish to know whether these data provide sufficient evidence to indicate that urokinase therapy lowers pulmonary artery pressure. Let \( \alpha=0.05 \). Use Wlcoxon matched pair test.

          \begin{tabular}{|l|l|l|l|l|l|l|l|l|l|}
\hline Patient & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline Before Therapy (X) & 33 & 17 & 30 & 25 & 36 & 25 & 31 & 20 & 18 \\
\hline After Therapy (Y) & 21 & 17 & 22 & 13 & 33 & 20 & 19 & 13 & 9 \\
\hline
\end{tabular}

We wish to know whether these data provide sufficient evidence to indicate that urokinase therapy lowers pulmonary artery pressure. Let \( \alpha=0.05 \). Use Wlcoxon matched pair test.

Patient 1 2 3 4 5 6 7 8 9

Before Therapy (X) 33 17 30 25 36 25 31 20 18

After Therapy (Y) 21 17 22 13 33 20 19 13 9

We wish to know whether these data provide sufficient evidence to indicate that urokinase therapy lowers pulmonary artery pressure. Let α=0.05. Use Wlcoxon matched pair test.

Step 1

- \( D = X - Y \) - For Patient 1: \( D_1 = 33 - 21 = 12 \) - For Patient 2: \( D_2 = 17 - 17 = 0 \) - For Patient 3: \( D_3 = 30 - 22 = 8 \) - For Patient 4: \( D_4 = 25 - 13 = 12 \) - For Patient 5: \( D_5 = 36 - 33 = 3 \) - For Patient 6: Show more…
