Question
A paper published in the New England Journal of Medicine reported that it didn't matter what your income, race, or insurance coverage was, you had only about a 50% chance of receiving the recommended medical care for the problem that was diagnosed. The study also reported numbers for those receiving the recommended care by age group. Assume that the data below was obtained and we have added the row and column totals to the observed frequencies: received did not receive total recommended recommended care care 18-30 yr 29 21 50 31-64 yr- 55 45 100 > 65 yr 26 24 50 total 110 90 200 We want to do a Chi-Square test of association for age range versus whether a patient received the recommended care or not. What is the expected frequency for the "31-64 yr" and "received recommended care" category? Round your answer to the tenths position.
