Question

which of these would not produce a representative sample that determines the favorite sport of the students at a local high school ​

Answer 1

Answer: The real answer is - ask 10 students wearing football jerseys each day for a week

Step-by-step explanation: Think about it, chances are that all students they ask that are wearing a football jersey are most likely to favor football. So if you only ask people with a football jersey on, you will not get an accurate answer to represent the entire high school. You should ask people randomly instead of targeting a specific group.
