Let PA and PB stand for the 1-year survival probabilities given treatment A and treatment B respectively. The null hypothesis is HO. PA - PB. Suppose data are collected, the survival is better in treatment A, and the p-value for this null hypothesis is found to be 0.023. Which of the following is a correct statement? Choose only one) O The probability that the null hypothesis is true is 0.023. We should reject the null hypothesis. O There is strong evidence against the null hypothesis. O Treatment A is substantially better than treatment B. O There is strong evidence in favor of the null hypothesis QUESTION 2 Considering the study in Question 1. suppose alternatively that data are collected and the survival is better in treatment A and the p-value for this null hypothesis is found to be 0.26. Which of the following is a correct statement? (Choose only one). O The probability that the null hypothesis is true is 0.26. We should reject the null hypothesis The treatments are equivalent. There is not strong evidence against the null hypothesis There is strong evidence in favor of the null hypothesis. QUESTION 3 Scenario: A study is designed to test the hypothesis that providing probiotics to infants reduces the incidence of gastrointestinal disease. The investigators plan to use a procedure which will have a type 1 error rate of 0 05. Given the sample size, the investigators will have 80% power if the probiotics resulted in a 50% reduction in gastrointestinal disease Based on this scenario, if the null hypothesis is true. what is the probability of rejecting the null hypothesis
