Final Answer:
An 18-year-old homeless Floridian would be considered in approximately the 78th percentile.
Step-by-step explanation:
To determine the percentile of an 18-year-old among homeless Floridians, we use the fact that 78% of the homeless population is 18 years and older. This means that 78% of the homeless fall into this age group or below.
Hence, an 18-year-old would fall within this 78%, indicating they are at or below the 78th percentile among homeless Floridians. Percentiles represent the percentage of values in a distribution that are equal to or below a certain value.
In this case, the 78th percentile suggests that 78% of the homeless population is 18 years old or younger. Therefore, an 18-year-old person would be within this range of 78% and not beyond it.
Understanding percentiles helps gauge where a particular data point falls within a distribution. In this scenario, an 18-year-old homeless person in Florida falls below approximately 78% of the homeless population in terms of age, making them a part of that percentile bracket.
