SOLUTION:
Case: Number of deaths
Method:
First, we add the total number of deaths
![\begin{gathered} 63+79+91+99+103+106+110+113+115+117+118+120+123+127+132+315+341+371+405+443 \\ =3491 \end{gathered}]()
Next, we subtract from the total number of people alive

If there were 244,000 48-year olds,
The scale factor will be:

Hence the number of people expected NOT to be alive is:

Final answer:
8519 people approximately
