4) For each food item, calculate the total percentage of people who became ill. (Total number of people who became ill divided by the total number of people).

5). Discuss your findings and explain how the study of epidemiology and use of descriptive statistics can assist in disease prevention. Submit your response as an APA page (at least one page) not counting the title page and reference page.
