Answer
In a sign-test, the test statistic is based on the hypothesis test and sample size. This is used to test the hypothesis regarding the median of the provided population. In a two-tailed sign test, k, which is called the test statistic, is a small number in the middle of positive signs and negative signs. In a two-tailed test, the hypothesis will be as follows:
\[\begin{align}
& {{H}_{0}}:\ M={{M}_{0}} \\
& {{H}_{1}}:\ M{{M}_{0}} \\
\end{align}\]
If k is less than the critical value, then H0 is rejected.
