In a statistical test, the null hypothesis is assumed to be true until proven otherwise. Therefore, the aim is to gather evidence that suggests that the null hypothesis should be rejected in favor of the alternative hypothesis. This means that the correct choice is to try to reject the null hypothesis (choice A). The other options are not correct: we are not trying to prove the alternative hypothesis (choice B), we do not choose a null hypothesis that is easy to reject (choice C), and we do not aim for a large level of significance if possible (choice D).
