Final answer:
Approximately 4,904 people in the town voted for the proposition, which represents 9.5% of the town's population of 51,623 people.
Step-by-step explanation:
To estimate how many people voted for the proposition in the town with a population of 51,623 people, we need to calculate 9.5% of that population. The calculation is as follows:
(9.5/100) × 51,623 = 4,904.185
Since the number of people cannot be a fraction, we approximate this to 4,904 people. This demonstrates a population proportion calculation which is a common mathematical exercise in understanding percentages and their practical applications in real world scenarios such as elections.
