Answer:
Correct option:
(1) the eastern gray squirrels that live in New York City's Central Park
Step-by-step explanation:
A population in Statistical analysis represents the set of all possible values a random variable, <em>X</em> can assume. For example, all the registered voters of the United States form a population, the weight of all the newborn babies in the country form a population.
All the mammals living in the region of Boulder, Colorado cannot form a population. This is because the set consists of <em>n</em> different species in the region.
And the gray squirrels and fox squirrels are two different species. So, together they cannot form a population.
The red foxes found east of the Mississippi River in the United States and in eastern Europe cannot form a population because the red foxes selected are from two different regions.
The eastern gray squirrels that live in New York City's Central Park can form a population because the set consists of one one species, i.e. the eastern gray squirrels from a particular region, i.e. New York City's Central Park.
Thus, the example of a population is "the eastern gray squirrels that live in New York City's Central Park."
