A store brand battery claims that it lasts as long as a more expensive national brand. A consumer watch dog group wants to make sure the claim being made by the store brand is not false, at 5% level of significance. The batteries were tested continuously by equipment mimicking normal use, and elapsed time until the batteries were no longer functioning was recorded. What is the alternative hypothesis is:

_store = _national

_{store national}

_store > _national

_store < _national

_{store national}
