Question

2. The health-care industry and consumer advocacy groups are at odds over the sharing of a patient’s medical records without the patient’s consent. The health-care industry believe that no consent should be necessary to openly share data among doctors, hospitals, pharmacies, and insurance companies.Suppose a study is conducted in which 600 patients are randomly assigned, 200 each, to three “organizational groupings”- insurance companies, pharmacies, and medical researchers. Each patient is given material to read about the advantages concerning the sharing of medical records within the assigned “organizational grouping.” Each patient is then asked “would you object to the sharing of your medical records with…”; the results are recorded in the following contingency table:

 

Object to Sharing Information

	Organizational Grouping
	Insurance	Pharmacies	Research
Yes	40	80	90
No	160	120	110

 

a. Is there evidence of a difference in objection to sharing information among the organizational groupings? (Use α = 0.05)
