A 7th grader student chooses a random sample of 50 out of 400 students. He finds that 7 students have traveled outside the Unite

malfutka [58]

If we assume the student’s sample is representative of the whole population, then yes, the student can be considered accurate.

7 / 50 = 0.14
400 * 0.14 = 56

About 56 of the 400 students can be estimated to have traveled outside the US.
