Answer 1

No, because he did not choose students randomly.

Tom's conclusion about the average number of musical instruments played by all students in the school is not valid because his sample was limited to students in two band classes, which may not accurately represent the entire student population. This could lead to bias in the results, as these students may play a different number of instruments compared to the general student body.
