It is possible for a hypothesis test to have differing conclusions as a confidence interval (with the appropriate corresponding significance/confidence level). The null hypothesis suggests that a difference exists, while the alternative hypothesis suggests that there is no difference. It is impossible for a p-value to exceed 1. It is possible for p-values to exceed 1. Question 9 (1 point) Which of the following statements is true? It is impossible for a p-value to exceed 1. It is possible for a hypothesis test to have differing conclusions as a confidence interval (with the appropriate corresponding significance/confidence level). Rejecting the null hypothesis means that the hypothesis test is failed. It is impossible for the test statistic to be negative.Question 10 (1 point) Which of the following statements is true?
