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.
What is the p-value if, in a two-tail hypothesis test, Upper Z Subscript STAT Baseline equals negative 2.04ZSTAT=−2.04?
