Perform the Indicated Wilcoxon Test $$\alpha =$$ 05

Perform the indicated Wilcoxon test. Be sure to do the following: Identify the claim mathematically and state the null
and alternative hypotheses. Determine the critical value and find the test statistic. Decide whether to reject or fail to
reject the null hypothesis and interpret the decision in the context of the original claim.
-A physician claims that a personʹs diastolic blood pressure can be lowered by listening to a relaxation tape each
evening. Ten subjects are randomly selected and their blood pressures are measured. The 10 patients then listen
to the tapes each evening for one month. At the end of the month, their blood pressures are measured again.
The data (in mm Hg)are listed below. Use the Wilcoxon signed-rank test to test the physicianʹs claim. Use $$\alpha =$$ .05. $$\begin{array} { l c c c c c c c c c c } \hline \text { Patient } & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\\hline \text { Before } & 83 & 82 & 99 & 86 & 90 & 80 & 91 & 94 & 92 & 81 \\\text { After } & 80 & 76 & 99 & 78 & 84 & 69 & 94 & 84 & 88 & 65 \\\hline\end{array}$$
