14. Graveley and Littlefield (A-27) conducted a study to determine the relationship between the cost and effectiveness of three prenatal clinic staffing models: physician based (1),

mixed (M.D., R.N.) staffing (2), and clinical nurse specialist with physicians available for consultation (3). Subjects were women who met the following criteria:

(a) 18 years of age or older or emancipated minors,

(b) obtained prenatal care at one of the three clinics with a minimum of three prenatal visits,

(c) delivered within 48 hours of the interview.
Maternal satisfaction with access to care was assessed by means of a patient satisfaction tool (PST) that addressed five categories of satisfaction: accessibility, affordability, availability, acceptability, and accommodation. The following are the subjects' total PST scores by clinic. Can we conclude, on the basis of these data, that, on the average, subject satisfaction differs among the three clinics? Let a = .05 and find the p value.
Use Tukey's procedure to test for differences between individual pairs of sample means.
