Problem
Objective: To compute and understand the use of odds ratio in epidemiologic research.
Instructions:
Review the following information and compose a one- to two-page paper in which you address the questions below.
There are 20 patients in your hospital ward. After an evening meal of BBQ or salad, seven of your patients are quite sick. You suspect something may have been wrong with the BBQ.
See the table below to demonstrate the numbers.

• Using the table above, what are the odds ratio for the relationship between eating the BBQ and not eating the BBQ? Show your work.
• With your findings, do you believe the BBQ was a possible cause for the sudden sickness in your ward? Explain your reasoning.
