A sample of depressed clients is treated with a new medication. For the general population of people with depression, the average symptom severity score is 29. After being treated with the new drug for a month, our small sample of clients have the following symptom severity scores: 23, 33, 26, 28, 30, 26, 27, 25, and 25.

Assume our question of interest is: Does the drug make some sort of difference in symptom severity? Use the .05 (5%) level of significance.

A) Reject Null

B) Fail to Reject Null

C) Reject Research Hypothesis

D) Fail to Reject Research Hypothesis

In regards to the question above (looking for a difference at the .05 or 5% level), what do our results suggest about the treatment?

A) insufficient evidence to suggest a treatment effect

B) our evidence indicates that the treatment increases symptom severity

C) our evidence indicates that the treatment reduces symptom severity

D) our evidence indicates the treatment makes a significant difference, but the direction of the effect is unknown.
