Questions 1 - 3 refer to the following:

Psychotherapist Dr. Leo Marvin is testing a new therapy that he thinks will lead to a rate of improved mood in his clients over a six-month period that is greater than chance. He uses the new therapy with 8 of his clients for six months. At the end of the period, he asks each client if their general mood has improved relative to when they started the new therapy.

RESULTS: 7 of the 8 clients report that their mood has improved.

Dr. Marvin will test his hypothesis using the six-step hypothesis testing procedure with the null hypothesis that improved mood is equally as unimproved mood and a false alarm rate of 0.05.

1. Which of the following best represent the null and alternative hypotheses for this experiment?

2. Which of the following represents the p-value for the experiment?

3. Dr. Marvin should reject the null hypothesis in favor of the alternative hypothesis.
