A study wants to know whether there is a difference in objection to sharing information among the three groups of customers: customers of insurance companies, customers of pharmacies and customers of medical researchers. A sample of customers is selected for each group and the results are as follows:

	Organizational Grouping
Object to Sharing Information	Insurance	Pharmacies	Research	Total
Yes	40	80	90	210
No	160	120	110	390
Total	200	200	200	600

At the = 0.025 level of significance, is there evidence of difference in objection to sharing information among the organizational groupings?
