A middle school has 450 students in a random sample of 100 students eight students indicated that they have traveled outside the United States predict the number of students at the middle school who have traveled outside the United States

Answer 1

To predict the number of students at the middle school who have traveled outside the United States based on the sample data, you can use a proportion.

In the sample of 100 students, 8 students indicated they have traveled outside the United States. This gives a proportion of:

\[ \text{Proportion} = \frac{8 \text{ students}}{100 \text{ students}} = 0.08 \]

Now, to predict the number of students in the entire school of 450 students who have traveled outside the United States, multiply the total number of students by the proportion:

\[ \text{Predicted number of students} = 450 \times 0.08 = 36 \]

So, you can predict that approximately 36 students at the middle school have traveled outside the United States.
