Type of Chocolate | Number of Chocolates followed | Number consumed | Number of Chocolates followed | Number consumed |
Nestle | 135 | 45 | 90 | 23 |
Cadbury | 123 | 55 | 68 | 21 |
Table E1.2. The number of chocolates that were observed to be consumed during the 6-hours of observation. Data are provided by the type of healthcare professional.
Healthcare Provider Position | Nestle | Cadbury | Provider total |
Doctor | 17 | 12 | 29 |
Nurse | 21 | 33 | 54 |

Question E1.3. If an independent survey found that 20% of all boxes of chocolates in hospitals were of the Cadbury brand, would you be able to calculate the population risk difference for consumption for the first 60 minutes after a box is opened? Assume that the Cadbury chocolates are the exposed group? If possible, calculate this quantity.
Question E1.4. What is the relative risk of Cadbury chocolate consumption among doctors versus nurses? Does this relative risk differ among other healthcare positions versus nurses?
