The criterion, often set at 0.05 (5%), defines the threshold for considering results statistically significant. If samples meet or exceed this criterion (occur more than 5% of the time), they are not considered unlikely or rare under the null hypothesis. Thus, statement B is not true as it contradicts the purpose of setting a significance level, which is to identify results that are unlikely to occur by chance alone.
