Which of the following is TRUE? a. The p-value should always be larger than the selected level of significance. b. If the p-value is smaller than the level of significance, then do not reject the alternate hypothesis. c. If we reject the null hypothesis, it is possible that p-value is larger than the selected level of significance. d. If the p-value is larger than the level of significance, then do not reject the null hypothesis.

QUESTION 2 Which of the following is TRUE? The p-value for a two tail test is less than the p-value for the corresponding one tail test. The calculated p-value should be divided by 2 to make the decision for a two tail test. The calculated p-value should be compared with the selected level of significance divided by 2 (a/2) to make the decision for a two tail test. O None of the above.
