In a normal approximation to the sign test, the standardised test statistic is calculated as z = -1.58. To test the alternative hypothesis that the location of population 1 is to left of the location of population 2, the p-value is: $\begin{array}{|l|l|}
\hline\text { A. } & 0.1142 . \
\hline \text { B. } & 0.2215 . \
\hline \text { C. } & 0.0571 \
\hline \text { D. } & 0.2284 \
\hline
\end{array}$
