Hello there.
Question: <span>A school principal wants to find out if his school needs more bike racks. a survey is taken of 30 students who ride their bikes to school. why might the sample be biased?
Answer: It might be biased as the survey was only taken of students who ride their bikes to school. It is most likely that they would agree to it. To make it fair they survey should have been taken of a variety of different students.
Hope This Helps You!
Good Luck Studying ^-^</span>
