The paper “Predictors of Complementary Therapy Use among Asthma Patients: Results of a Primary Care Survey” (Health and Social Care in the Community : 155–164) included the accompanying table. The table summarizes the responses given by 1077 asthma patients to two questions: Question 1: Do conventional asthma medications usually help your asthma symptoms? Question 2: Do you use complementary therapies (such as herbs, acupuncture, aroma therapy) in the treatment of your asthma?
From this information, we can estimate that the proportion who use complementary therapies is
For those who report that conventional medications usually help, the proportion who use complementary therapies is 131/947 = .138 and for those who report that conventional medications usually do not help, the proportion who use complementary therapies is 27/130 = .208. If one of these 1077 patients is selected at random, are the outcomes selected patient reports that conventional medications usually help and selected patient uses complementary therapies independent or dependent? Explain.
