Answer:

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.

Step-by-step explanation:

From the random sample, we can expect that \frac{250000}{500000}=\frac{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 \frac{1}{2} = 7950000 students to have played on a sports team that year.
