Question

Transcribed Image Text: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

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?
