In hypothesis testing, we compare the probability level (p-value) of our experiment to the pre-determined alpha level. If the p-value is smaller than the alpha level, we reject the null hypothesis. In this case, the probability level is 0.04 which is smaller than the alpha level of 0.05. Therefore, we reject the null hypothesis.
