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 middle school who have traveled outside the United States. (1 point)
36 students
To predict the number of students at the middle school who have traveled outside the United States, you can use the concept of proportions.
Step 1: Find the proportion of students in the random sample who have traveled outside the United States.
Proportion = (Number of students who have traveled outside the United States) / (Total number of students in the random sample)
Proportion = 8 / 100
Proportion = 0.08
Step 2: Use the proportion to estimate the number of students in the entire middle school who have traveled outside the United States.
Number of students who have traveled outside the United States = (Proportion) x (Total number of students in the middle school)
Number of students who have traveled outside the United States = 0.08 x 450
Number of students who have traveled outside the United States ≈ 36
Therefore, the prediction is that approximately 36 students at the middle school have traveled outside the United States.
