When to write null hypothesis and alternative hypothesis?

Why is failing to reject the null hypothesis weak?
Failing to reject the null hypothesis—that the results are explainable by chance alone—is a weak conclusion because it allows that factors other than chance may be at work but may not be strong enough to be detectable by the statistical test used.
