Researchers conduct a case-control study to investigate the association between ever smoking and lung cancer.They recruit 172 people with lung cancer and 6,500 people without lung cancer to participate. They administer a survey to the participants asking whether they ever smoked cigarettes. Among the participants with lung cancer, 127 had ever smoked and among the participants without lung cancer, 3,400 were ever smokers. Based on this scenario, please help me understand by responding to the following:

• Create the appropriate 2x2 table for the data in the scenario. [Organize/Display Data]
• Calculate the odds ratio for the relationship between ever smoking cigarettes and lung cancer. [Calculate]
• Explain the numerical interpretation of the odds ratio calculated in #15. [Interpret]
• Calculate the odds ratio for the relationship between never smoking cigarettes and lung cancer. [Calculate]
• Explain in a narrative the numerical interpretation of the odds ratio you calculated in #17. [Interpret]
• Discuss whether to agree or disagree with the following statement and why: Calculating an odds ratio requires access to incidence data. [Using Data]
