amiddle school has 450students. in random sample of 100 students, 8 students indicated that they have traveled outside the United states. Perdict 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 use the proportion of students in the sample who have traveled outside the United States as an estimate for the entire population.
Given:
Total number of students in the middle school = 450
Number of students in the sample who have traveled outside the United States = 8
Number of students in the sample = 100
Proportion of students in the sample who have traveled outside the United States = 8/100 = 0.08
Now, to predict the number of students at the middle school who have traveled outside the United States, we can use the proportion calculated above:
Number of students who have traveled outside the United States = 0.08 * 450 = 36
Therefore, it is predicted that approximately 36 students at the middle school have traveled outside the United States.
