C) high alphas but low degrees of freedom.
D) high alphas, large samples, and one- tailed tests.

Question

Quizplus · Accepted Answer

To maximize the probability of rejecting the null hypothesis, we need to choose a higher alpha level, a large sample size, and a one-tailed test as it has a smaller critical value and thereby increasing the chance of rejecting the null hypothesis. A low alpha level and a two-tailed test will reduce the chance of rejecting the null hypothesis. Choosing low alphas and high Z scores are not necessarily connected to maximizing the probability of rejecting the null hypothesis. High alphas but low degrees of freedom would not give a reliable result for the statistical test.
