The two approaches to significance testing are p-value approach and critical value approach.
In p-value approach, the data gives strong evidence to reject the null hypothesis when it is too small (<0.01). The conclusion of the p-value approach is based on the comparison between p-value of the test and the significance level, $\alpha$.
Decision:
If p-value is less than or equal to the significance level, the null hypothesis is rejected.
In critical value approach, if the test statistic lies in the critical region, then the null hypothesis is rejected. The conclusion of the critical value approach is based on the comparison between test statistic of the test and the critical value at $\alpha$ of the test .
Decision:
If critical value is greater than the test statistic, the null hypothesis is rejected.
