Question

It is known that AIDS patients often develop respiratory complications. A study of the risk factors is conducted. Of the 2009 patients in the study, 1000 have a smoking history and 1500 have respiratory complications. 90% of the patients with a smoking history have respiratory complications. The relative risk, ρ, for respiratory complications associated with smoking is defined as:

ρ = P (respiratory complication∥smoking) /P(respiratory complication∥not smoking)

Based on this data, determine the relative risk ρ for respiratory complications associated with smoking. Interpret the result.
