- What is meant by the sample space of an experiment?It will lead us to reject the null hypothesis and accept the other region represented by the alternative hypothesis. A. Test Statistic B. Critical Region C. Two-sample mean Test D. One-sample mean TestWhich of the following statements is consistent with hypothesis testing? a. If conducted correctly, hypothesis testing eliminates the risk of error. b. A low alpha level increases the size of the critical region(s). c. The edges of the distribution of sample means are consistent with the alternative hypothesis. d. All else equal, a one-tailed hypothesis test requires a more extreme treatment effect to detect statistical significance than a two-tailed hypothesis test.
- If difference scores begin to pile up away from a sample mean difference score of MD = 0, which of the following statements is true? The null hypothesis will likely fail to be rejected. The null hypothesis will likely be rejected. The sample size is large. The critical region is small.Which of the following statements is true about the null hypothesis? Question 1 options: It is a statement that directly contradicts the null hypothesis Often includes a < or > sign or states that something is not equal We determine whether or not to reject this statement based on the likelihood of the opposite hypothesis being true It is a statement about the population parameter Question 2 True or False? A small p-value indicates strong evidence against the null hypothesis Question 2 options: True False Question 3 Which statement is incorrect? Question 3 options: Strong evidence against the null is indicated by a p-value less than 0.05 Weak evidence against the null is indicated by a p-value greater than 0.05 Marginal evidence against the null is indicated by a p-value around 0.05 All are…Which of the following relates to the rejection of the null hypothesis when it is actually true? 1.
