Short Answer

Write the word or phrase that best completes each statement or answers the question.
-A football coach believes that a player can increase strength by taking vitamin E. To test the theory, the coach randomly selects 9 athletes and gives them a strength test using a bench press. The results are listed below. Thirty days later, after regular training supplemented by vitamin E, they are tested again. The new results are listed below. Use the Wilcoxon signed-ranks test to test the hypothesis that the vitamin E supplement is effective in increasing the athletes' strength. Use $\alpha = 0.05$ .
$\begin{array}{lccccccccc}\text { Athlete } & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\\hline \text { Before } & 206 & 185 & 207 & 182 & 266 & 228 & 242 & 217 & 225 \\\text { After } & 216 & 190 & 207 & 180 & 273 & 243 & 247 & 212 & 230 \\\hline\end{array}$
