Question

A seventh grade student chooses a random sample of 50 out of 400 students. He finds that 7 students have traveled outside the United States. The students claim that over 50 of the 400 students have likely traveled outside the United States. Is the student correct? Explain.

Answer 1

Yes.

Explanation:

Since he only sampled 50/400, 50 of 400 is 1/8.

7x8=56.
