The null hypothesis must always include the concept of equality, which means that it must include the logical operators equal, less than or equal, or greater than or equal. On the other hand, the alternative hypothesis must always express the opposite of the operator used for the null hypothesis, which means it should always include the operator not equal, greater than, or less than.

Si la hipótesis nula expresa igualdad, la hipótesis alternativa expresa desigualdad.
Si la hipótesis nula expresa menor o igual a, la alternativa expresa mayor a.
Si la hipótesis nula expresa mayor o igual a, entonces la alternativa expresa menor a.
The null hypothesis must always include the concept of equality, which means that it must include the operators equal, less than or equal, or greater than or equal.
