4. A team of psychologists designed a study in which 12 psychiatric patients diagnosed as having generalized anxiety disorder were randomly assigned to one of three new types of therapy, here labeled X, Y, and Z. One year after therapy, the patients’ overall mental health scores were as follows:

Mental Health Assessment
Therapy X      Therapy Y         Therapy Z
85            78            79
79            81            83
84            68            75
67            75            74

   Do these results suggest that the different therapies have different effects on mental health?
(Use the .05 level.)
a.   Use the five steps of hypothesis testing.
b.   Sketch the distribution involved.
c.   Explain your results.

When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.
