If the value of the test statistic is in the rejection region, it means that the probability of obtaining such a result by chance is less than the significance level (usually set at .05). Therefore, p < .05. The decision in this case is to reject the null hypothesis. This also means that the value of the test statistic is larger than the critical value, which is another way to define the rejection region. Therefore, all of these statements are true.
