To find the expected number of Black non-Hispanic students in a U.S. public school with 1,000 students, we can use the percentage representation from the pie chart.
The pie chart shows:
- Black non-Hispanic: 17%
To calculate the number of Black non-Hispanic students:
\[ \text{Number of Black non-Hispanic students} = \frac{17}{100} \times 1000 \]
Calculating this gives:
\[ \text{Number of Black non-Hispanic students} = 0.17 \times 1000 = 170 \]
Therefore, the expected number of Black non-Hispanic students in the school is 170.
