A middle school has 450 students. In a random sample of 100 students, 8 students indicated that they have traveled outside the United States. Predict the number of students at the missle school who have traveled outside the United States.

__ students

To predict the number of students at the middle school who have traveled outside the United States, we can use the proportion from the sample to estimate the total number of students.

First, calculate the proportion of students in the sample who have traveled outside the United States:
Proportion in sample = Number of students in sample who have traveled / Total number of students in sample
Proportion in sample = 8 / 100 = 0.08

Next, use this proportion to estimate the total number of students in the middle school who have traveled outside the United States:
Estimated number of students = Proportion in sample * Total number of students in the middle school
Estimated number of students = 0.08 * 450 = 36

Therefore, we can predict that around 36 students at the middle school have traveled outside the United States.
