For a hypothesis to be statistically significant it needs to be at the very least 5% to reject the null.

No, the p-value has to be at least 5% to reject the null. Assuming a is 5% and it's a one tailed test not two tailed..

And of course there are huge problems with using a flat 5% is a statistical significance marker, BSAP banned it's use.

Finish your stats class and try again.

That's not how statistics works. You can have a significant effect with a tiny effect size, or a large effect size that on analysis turns out to be insignificant.
