om wants to know the average number of musical instruments students in his school play. He used the school’s two band classes, consisting of a total of 48 students, as his representative sample. He concluded that students in his school play an average of three musical instruments. Is his conclusion valid?(1 point)

Yes, because the sample includes both males and females who play musical instruments.
Yes, because all members of the sample play at least one musical instrument.
