In the two examples for the signtest function of non-parametric estimation in matlab shown in https://www.mathworks.com/help/stats/signtest.html#bti4471-7, the p-values do not affect the hypothesis tesing outcome. Is this correct? Please help with a clarification if you used it often, it is very much appreciated. AUSER

From the documentation:
[p,h] = signtest(___) also returns a logical value indicating the test decision. The value h = 1 indicates a rejection of the null hypothesis, and h = 0 indicates a failure to reject the null hypothesis at the 5% significance level.
Also see the documentation for h.

You can examine the code
edit signtest
Near the end you will see
h = (p<=alpha);

The error is with the example not the code then, could be a typo with the documentation. Thank you!

The code in the last answer pinpoints the error location and nature.
