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
To predict the number of students at the middle school who have traveled outside the United States, we can set up a proportion.
Let x be the number of students at the middle school who have traveled outside the United States.
Based on the given information, we have the following proportion:
8/100 = x/450
To solve for x, we cross-multiply:
100x = 8 * 450
100x = 3600
Divide both sides by 100:
x = 3600/100
x = 36
Therefore, it is predicted that there are 36 students at the middle school who have traveled outside the United States.
