Can you reject the null hypothesis at the 0.01 significance level?

WebWe use p p -values to make conclusions in significance testing. More specifically, we compare the p p -value to a significance level \alpha α to make conclusions about our hypotheses. If the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a. WebTraditionally, experimenters have used either the 0.05 level (sometimes called the 5% level) or the 0.01 level (1% level), although the choice of levels is largely subjective. The lower the significance level, the more the data must diverge from the null hypothesis to be significant. Therefore, the 0.01 level is more conservative than the 0.05 ...
