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. O We should reject the null hypothesis. O There is strong evidence against the null hypothesis. O Treatment A is substantially better than treatment B. There is strong evidence in favor of the null hypothesis. QUESTION 2 1 p 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.
