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) students
To predict the number of students at the middle school who have traveled outside the United States, we can use the concept of proportions.
First, we find the proportion of students in the sample who have traveled outside the United States:
Proportion = (Number of students in the sample who have traveled outside the US) / (Total number of students in the sample)
Proportion = 8/100 = 0.08
Next, we can use this proportion to estimate the number of students in the middle school who have traveled outside the United States:
Number of students outside the US = Proportion * Total number of students
Number of students outside the US = 0.08 * 450 = 36
Therefore, the predicted number of students at the middle school who have traveled outside the United States is 36.
