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 is the standard error of the natural log of the hazard ratio for the disease group relative to the healthy group?
