Consider the data table showing epidemiology data for 25 individuals with a disease and 25 healthy comparison individuals. Their deaths are recorded over a period of 12 months.

$\begin{array}{c}
\underline { \text { Diseased } } \quad \quad \quad \quad \quad \quad \quad \quad\underline { \text { Healthy}}\
\begin{array}{cccc}
\text { Time } & \text { \# at risk } & \text { Deaths } & \text { \# at risk } & \text { Deaths } \
2 & 25 & 1 & 25 & 2 \
4 & 24 & 3 & 23 & 5 \
6 & 21 & 1 & 18 & 4 \
8 & 20 & 2 & 13 & 3 \
10 & 18 & 0 & 10 & 1 \
12 & 18 & 1 & 9 & 2
\end{array}\end{array}$
-What are the total number of expected deaths for the diseased and healthy groups, respectively?

The total number of expected deaths for the diseased group is 13.95 and for the healthy group is 11.05. This can be calculated using the formula:Expected deaths = (Number at risk / Total number at risk) * Total deathsFor the diseased group, this would be:(25 / 50) * 17 = 13.95For the healthy group, this would be:(25 / 50) * 17 = 11.05
