-------
Hypothesis:
The three treatments tested differ in how well they work.
It's a question of equality, so 2-tail test.
Type I: Reject equality when it is true
Type II: Fail to reject equality with it is false.
==========================================================
Children receiving supportive therapy will get worse over time (at posttreatment).
It a question of "worse than", so a right-tail test.
Type I: Accept the "worse than" when it is false.
Type II : Reject the "worse than" when it is true.
