Question

Helppppppppp

In a recent year, there were 15,900,000 high school
students in the United States. Suppose 250,000 of a
random sample of 500,000 high school students
during that year played on a sports team. Estimate
the total number of U.S. High school students that
played on a sports team that year.

Answer 1

The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.

Explanation:

From the random sample, we can expect that
`(250000)/(500000)=(1)/(2)` of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect
`15900000 \cdot (1)/(2) = 7950000` students to have played on a sports team that year.
