Let $x _ { 1 } , x _ { 2 } , \ldots , x _ { 10 }$

Short Answer

Let $x _ { 1 } , x _ { 2 } , \ldots , x _ { 10 }$ be a random sample from a continuous and symmetric probability distribution with mean (and median) $\mu .$ In testing $H _ { o } : \mu = 100 \text { versus } H _ { a } : \mu > 100$ using the Wilcoxon signed-rank test, the rejection region for level .01 test is $s _ { + } \leq$$\underline{\quad\quad}$
