Question
There are four aferent CIINIcal sites In a small cty, patients In each site are enrolled and randomly receive either the experimental medication designed to lower blood pressure or placebo, then the patients blood pressure measured after 5 hours. Data is given in the following table: Treatment Site 1 Site 2 Site 3 Site 4 Hypertensive 27 56 45 62 No Hypertensive 58 69 53 19 Test if there is a difference in the proportions of hypertensive patients across clinical sites. Run the Chi-Squared test at a 5% level of significance and clearly state hypotheses, test statistic and conclusion. a. b) Fit independent and saturated loglinear models for these data. Is there sufficient evidence to indicate that there is a relationship between treatment and site? Compare two models by "anova".
