A manufacturer of baseball hats claims that approximately 30% of people regularly wear baseball hats. From a random sample of 20 students at your school, you find that only four wear baseball hats regularly. This gives you reason to believe that the manufacturer’s claim of 30% is too high.

Let the digits 0–2 represent wearing a baseball hat (H) and the digits 3–9 represent not wearing a baseball hat (N). Use the table of random numbers to run one trial of this simulation.

Which is the correct sequence of outcomes?

NNNNN HHNNN NNNHN NHNHN

HHHHH NNNNN NNNNN NNNNN

NHNHN HNHNH NHNHN HNHNH

HHHHH NNHHH HHHNH HNHNH
