L. Petersen et al. evaluated the effects of integrated treatment for patients with a first episode of psychotic illness in the paper A Randomised Multicentre Trial of Integrated Versus Standard Treatment for Patients with a First Episode of Psychotic Illness (British Medical Journal, Vol. 331, (7517):602). Part of the study included a questionnaire that was designed to measure client satisfaction for both the integrated treatment and a standard treatment. The data on Blackboard labeled as Psychotic Medical Trial are based on the results of the client questionnaire. a) Download the file to your computer, and import the data psychotic.csv into R. b) Obtain means and the standard deviations for the two samples and present them. c) Draw qqplots and boxplots (review MATH 1051H workshops if you don't remember how these work) for the two samples. d) Based on your results from part (b), which would you be inclined to use to compare the population means: a pooled or a non-pooled t-procedure? Explain your answer. (use Section 7.3.4 in the text for review) e) At the 2% significance level, do the data provide sufficient evidence to conclude that, on average, clients preferred the integrated treatment? (if you are careful, you may use t.test() for this - you have to set all the arguments!) f) Find a 94% confidence interval for the difference between mean client satisfaction scores for the two treatments. Interpret the CI. L.
