The significance level for a Wilcoxon signed rank sum test is 0.05. The alternative hypothesis is stated as: The location of population 1 is to the left of the location of population 2. The appropriate critical value for a sample of size 20 (that is, the number of nonzero differences) is: $\begin{array} { | l | l | }
\hline \text { A. } & 158 . \
\hline \text { B. } & 150 . \
\hline \text { C. } & 60 \
\hline \text { D. } & 52 \
\hline
\end{array}$
