Question

.   A sample of 55 withdrawn schizophrenic adolescents was studied to determine if art therapy significantly decreases hallucinations.   The level of significance was set at 0.05. The results of the study indicated that hallucinations after art therapy decreased from a mean score of 5.0 to 3.0 with a probability of .002

        Set up the 6 step research process using the above data, omitting the specific test statistic and calculations. (In actual problems in the upcoming units, you WILL include both the statistics and calculations.) In order to help conceptualize, draw the normal curve which represents the problem. This curve is only for you and does not have to be turned in. (10 points)
