Answer 1

The most appropriate response to Tom's conclusion is:

No, because he did not choose students randomly.

While he gathered data from the two band classes, this sample may not be representative of the entire school population since it is limited to students already enrolled in band. Therefore, the conclusion about the average number of instruments played by all students in his school may not be valid.
