Homework
Read the "Oswego Outbreak Investigation," located in the Topic Materials.
Part I
Complete the following:
i. Using the line listing in the Excel "Oswego Line Listing Workbook," calculate the attack rate ratios for each food item using the table in the Excel "Oswego Attack Rate Table."

Refer to the "Creating a 2x2 Contingency Table" resource for guidance.
