Using the data in the table below, calculate the Incidence Proportion as a decimal for each of the four weeks of the foodborne outbreak.

Complete the calculations for boxes a - d marked on the table on scratch paper, and then respond.

**Table - Cases of Foodborne Illness at School Cafeteria during 4 weeks of an outbreak**

| **Week**   | **New Cases of Foodborne Illness** | **Total Cases of Foodborne Illness** | **Number of People Who ate at Cafeteria** | **Incidence (as a decimal)** |
|------------|-------------------------------------|--------------------------------------|-------------------------------------------|-------------------------------|
| Nov 1-7    | 3                                   | 3                                    | 300                                       | a                             |

To calculate the incidence proportion as a decimal for each week, divide the number of new cases by the number of people who ate at the cafeteria during that week.

For example, for the week of Nov 1-7:

\[ \text{Incidence} = \frac{\text{New Cases}}{\text{Number of People Who ate at Cafeteria}} = \frac{3}{300} = 0.01 \]

Repeat this calculation for each week to find the values of a, b, c, and d.
