one cannot make decisions or draw conclusions that assume the truth of the null hypothesis. Just as failing to reject it does not "prove" the null hypothesis, one does not conclude that the alternative hypothesis is dis-proven or rejected, even though this seems reasonable. One simply concludes that the null hypothesis is not rejected.[clarification needed] Not rejecting the null hypothesis still allows for getting new data to test the alternative hypothesis again. On the other hand, rejecting the null hypothesis only means that the alternative hypothesis may be true, pending further testing.
