Your results are statistically significant. When your p-value is greater than your significance level, you fail to reject the null hypothesis.

WebTo decide if we have sufficient evidence against the null hypothesis to reject it (in favour of the alternative hypothesis), we must first decide upon a significance level. The significance level is the probability of rejecting the null hypothesis when it the null hypothesis is true and is denoted by $\alpha$. WebTherefore, our initial assumption that the null hypothesis is true must be incorrect.
