Textbook Question
Chapter 15, Problem 11P
Mulvihill, Obuseh and Caldwell (2008) conducted a survey evaluating healthcare providers' perception of a new Mate children’s insurance program. One question asked the providers whether they viewed the reimbursement from the new insurance as higher, lower, or the same as private insurance. Another question assessed the providers’ overall satisfaction with the new insurance. The following table presents observed frequencies similar to the study results.
| Satisfied | Not Satisfied | ||
| Less Reimbursement |
46 | 54 | 100 |
| Same or More Reimbursement | 42 | 18 | 60 |
| 88 | 72 |
Do the results indicate that the providers' satisfaction of the new program is related to their perception of the reimbursement rates? Test with α = .05.
