If a hypothesis is rejected at a 5% level of significance, it means that there is less than a 5% chance that the result was due to chance. However, this does not necessarily mean that the hypothesis will always be rejected at the 1% level. The 1% level of significance is even more strict, therefore it may be possible that the hypothesis cannot be rejected at this level. Hence, the hypothesis may be rejected or not rejected at the 1% level.
