- A recent outbreak of E. Coli at your favorite restaurant prompts you to take a survey of friends to see if a certain food was causing the outbreak. You ask 96 friends who ate at the restaurant recently if they ate a salad or burrito (let's assume there are only two options on the menu) and whether they got sick or not. Â Did they get sick? Food Choice Sick Not Sick Total Salad 20 11 15 Burrito 20 55 75 Total 24 66 90 Responses Getting sick is independent of food choice. Your probability of getting sick does not change based on what food you ate. You are more likely to get sick if you eat a burrito. Getting sick is dependent on food choice. You are more likely to get sick if you eat a salad. Your probability of getting sick changes based on what food you ate.arrow_forwardHow do you calculate a cohen's, why and when?
