Question: The health-care industry and consumer advocates are at odds over the sharing of a patient’s medical records without the patient’s consent. The health-care industry believes 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 and disadvantages 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…” and the results are recorded in the cross-classification table below.

	Organizational Grouping
OBJECT TO SHARING INFORMATION	Insurance	Pharmacy	Research
Yes	40	80	90
No	160	120	110

a. Is there evidence of a difference in the proportions who object to sharing information among the organizational groupings? (Use α = .05.)

Complete the following:
1. State H₀.	There is NO difference in the proportions who object to sharing information among the organizational groupings
2. State H₁.	There is a difference in the proportions who object to sharing information among the organizational groupings
3. State the value of α.	0.05
4. State the value of the test statistic.	30.77
5. State the p-value.	0.000000208
6. State the decision in terms of H₀ and why.	Reject the null hypothesis (p > 0.05)
7. State the decision in terms of the problem.	There is enough evidence to claim that There is a difference in the proportions who object to sharing information among the organizational groupings
